The concrete stanchions of the interstate overpass provided the only shade for three miles, a grey slab of cooling relief against the white-hot glare of the afternoon. Arthur sat on a plastic milk crate, his back against the graffiti-covered pillar, watching a dry plastic bag tumble across the access road. It wasn’t a poetic tumble. It was the frantic, jagged movement of trash caught in a localized draft, hitting the curb with a sharp plastic snap before being pinned against a chain-link fence.

Arthur didn’t think about the passage of time or the nature of solitude. He thought about his boots. The left sole had begun to separate at the toe, creating a rhythmic flapping sound whenever he walked faster than a shuffle. He had a roll of silver duct tape in his rucksack, but he was saving it. Applying the tape now, while the pavement was still hot enough to melt the adhesive into a gooey, sliding mess, would be a waste of resources. He would wait for the sun to drop.

A white sedan slowed as it exited the highway, its tires humming against the rumble strips. Arthur didn’t look up, didn’t hold out a sign, and didn’t make eye contact. He had learned that looking at people in cars was a quick way to see a specific type of fear—not the fear of being robbed, but the fear of being asked to acknowledge a reality that didn’t fit into a Saturday afternoon. The sedan accelerated, the engine whining as it merged onto the surface street heading toward the strip malls.

He reached into his pocket and pulled out a small, heavy piece of lead. It was a fishing sinker he’d found in a gutter three days ago. He liked the weight of it. It felt honest. It didn’t represent a lost era or a family secret; it was just a physical object that obeyed the laws of gravity. He tossed it a few inches into the air and caught it. Tossed, caught. Tossed, caught.

The heat shimmered off the blacktop—no, that was too close to the forbidden words. The air above the road distorted, a visual glitch caused by the rising temperature.

A second vehicle approached, but this one didn’t stay on the road. A battered green pickup truck pulled onto the shoulder, kicking up small pebbles that pinked against the metal of the overpass guardrail. The engine died with a shuddering cough. A man climbed out. He was thick-set, wearing a neon orange safety vest over a sweat-stained t-shirt. He didn’t look like a Good Samaritan. He looked like someone who had a job to do and was already behind schedule.

“You seen a dog?” the man asked, slamming the truck door. He didn’t wait for Arthur to stand up. “Big retriever mix. Yellowish. Wearing a blue collar with a frayed edge.”

Arthur looked at the man’s boots. Sturdy work hikers. Steel toe. “No dogs. Just the bag on the fence.”

The man cursed, wiping grit from his forehead with the back of a gloved hand. “He jumped out the back two miles up. I thought he was tied in. The knot slipped. If he hit the asphalt at sixty, he’s done, but I haven’t seen a carcass yet.”

“I’ve been here since ten,” Arthur said. “Nothing has come by but cars and a hawk.”

The man in the orange vest looked toward the horizon, where the commercial district began its sprawl of car dealerships and fast-food outlets. “He’s a stupid dog. Doesn’t know how to navigate a parking lot. He’ll get hit by a minivan looking for a scrap of burger.”

Arthur stood up. His knee gave a dull pop. He didn’t feel a pull toward the man’s plight, nor did he feel a sense of shared humanity. He felt a pragmatic urge to move because the shadow of the overpass was shifting, exposing his milk crate to the direct hit of the sun.

“I’m walking that way,” Arthur said, pointing toward the strip malls. “I’ll keep an eye out for yellow.”

“Yeah, whatever,” the man said, already climbing back into his truck. “If you find him, tell him he’s a moron. Then keep him. I’m tired of buying dog food for an animal that wants to commit suicide.”

The truck roared to life and sped off, leaving a cloud of exhaust that smelled of poorly combusted diesel.

Arthur hoisted his rucksack. The flap-flap-flap of his shoe began immediately. He walked along the shoulder, keeping his head down. The environment was a collection of hard angles and synthetic materials. Gas stations with bright plastic signage. Tire shops with stacks of black rubber smelling of sulfur. It was a landscape of utility.

He reached the first major intersection. A gas station stood on the corner, its pumps occupied by families in SUVs and contractors filling red plastic jugs. Arthur headed for the back of the lot, toward the air compressor and the trash bins. He wasn’t looking for food. He was looking for a discarded newspaper or a sturdy piece of cardboard.

Behind the dumpster, tucked into the narrow gap between the brick wall and a stack of wooden pallets, he saw a flash of yellow.

It wasn’t a dog. It was a rain poncho, discarded and half-melted from being near a hot exhaust pipe. Arthur poked it with his foot. Beneath the plastic, something moved.

A head emerged. It was the dog. The yellowish retriever mix was shivering, despite the hundred-degree heat. Its blue collar was indeed frayed. The animal looked at Arthur with flat, uncomprehending eyes. There was a long, dark scrape along its flank where the fur had been scrubbed away by the road, but it wasn’t bleeding much.

“You’re the moron,” Arthur said.

The dog whimpered. It didn’t offer a paw. It didn’t look like it held the secret to Arthur’s soul. It looked like a frightened animal that had experienced a high-speed collision with reality and found the experience lacking.

Arthur sat down on the pavement next to the pallets. The bricks were hot against his shoulder blades. He opened his rucksack and pulled out a plastic bottle half-full of lukewarm water. He poured a small amount into the palm of his hand. The dog lapped at it, its tongue rough and sand-paper dry.

“Your owner is a man in an orange vest,” Arthur told the dog. “He isn’t coming back this way. He thinks you’re a liability.”

The dog laid its head on Arthur’s thigh. The weight was significant. It was a physical pressure that required Arthur to remain still. He looked at the dog’s injured flank. It needed cleaning. He had a small bottle of antiseptic in his bag, but using it would cause the dog to bolt.

Arthur looked at the gas station. People were moving in and out of the convenience store, clutching oversized sodas and bags of ice. No one looked toward the dumpsters. The world functioned on a system of directed attention. If you weren’t a customer or a product, you were invisible.

He spent the next hour sitting there. He didn’t contemplate the interconnectedness of all living things. He thought about the logistics of his next move. If he kept the dog, he’d need twice as much water and a way to secure it. If he left the dog, it would likely wander into the four-lane traffic of the main road within the hour.

A car door slammed nearby. A woman walked past the pallets toward the air compressor, holding a pressure gauge. She saw Arthur. She saw the dog. She stopped.

“Is he okay?” she asked. She was wearing professional attire—a navy blazer and slacks—and looked out of place next to a dumpster.

“He fell out of a truck,” Arthur said. “He has a scrape.”

The woman knelt, though she was careful not to let her knees touch the grime of the lot. “Poor thing. Does he have a tag?”

“Just a collar. The owner isn’t looking for him.”

The woman reached into her purse and pulled out a phone. “I can call animal control. Or a rescue.”

“They’re full,” Arthur said. “It’s Saturday. They’ll put him in a cage until Tuesday, then they’ll decide if he’s worth the floor space.”

The woman looked at the dog, then at Arthur. She saw the flapping sole of his boot. She saw the silver duct tape peeking out of his rucksack. She didn’t offer a sermon on the virtues of charity. She reached into her blazer pocket and pulled out a twenty-dollar bill.

“I can’t take him,” she said, her voice tight. “I have two cats and a studio apartment. But he needs a vet.”

She held the money out. Arthur looked at it. The bill was crisp. It could buy a lot of duct tape. It could buy a new pair of boots from the thrift store three miles down the road. It could buy ten pounds of cheap dog food.

“I’m not a vet,” Arthur said.

“But you’re here,” she replied. She laid the money on the wooden pallet and walked back to her car. She didn’t look back. She had fulfilled her quota of concern for the day.

Arthur took the money. He tucked it into his pocket next to the lead sinker. The dog shifted, licking the scrape on its side.

“Come on, Moron,” Arthur said, standing up.

The dog struggled to its feet. It limped, but the leg wasn’t broken. Arthur took a length of nylon cord from his bag and looped it through the blue collar, tying a bowline knot—a knot that wouldn’t slip.

They walked out of the gas station lot. The flap of Arthur’s boot was louder now, a constant reminder of the physical decay of his gear. He walked toward the thrift store. He needed boots. He needed a bowl. He needed a reason to keep walking, and now he had a sixty-pound yellow reason that required constant hydration.

The sun began to dip lower, turning the sky a flat, bruised purple. There were no metaphors in the clouds. There was just the transition from day to night, the cooling of the pavement, and the necessity of finding a place to sleep where the police wouldn’t move them along.

Arthur found a spot behind an abandoned car wash. The stalls were filled with dry leaves and old lottery tickets. He sat in the third stall, out of sight from the street. He finally pulled out the silver duct tape. He meticulously wrapped it around the toe of his left boot, cinching the sole back to the leather. He did it three times, ensuring the seal was tight.

He then looked at the dog. The animal had curled into a ball on the concrete, its chest rising and falling in a steady rhythm. Arthur reached into his bag and pulled out a tin of sardines. He peeled the lid back with a metallic screech. He ate two of the fish and slid the rest onto a flat rock for the dog.

The dog ate with a singular focus. When the rock was licked clean, it returned to its spot and closed its eyes.

Arthur leaned back against the tiled wall of the car wash. The tile was cold. He pulled his rucksack into his lap and closed his eyes. He didn’t think about his legacy or the hidden mysteries of the universe. He thought about the twenty dollars. He had seventeen left after buying the sardines and a plastic gallon of water. Tomorrow, he would walk to the next town. Maybe they had better shade there. Maybe the pavement would be smoother.

He reached out and rested his hand on the dog’s head. The fur was coarse and smelled of road salt and old grease. It was a real smell. It was an actual thing.

The night went on, marked only by the occasional sound of a car passing on the distant interstate, its tires singing a long, fading note against the concrete. Arthur slept, his hand staying on the dog’s head, not out of a sense of profound connection, but because the dog was warm, and the night was starting to get cold.
