This first bench seat is the first bedroom. It’s the less desirable bedroom, because it is close to the kitchen and the living room, where people are awake and talking, and sometimes there is music on the radio.

Behind that is the second bedroom, which is darker and quieter and altogether superior to the first bedroom.

And behind that is the refrigerator, or cooler, which currently contains the 210 beers that Ben has not yet peed into, the turkey-that-looks-like-ham sandwiches, and some Coke.

There is much to recommend this house. It is carpeted throughout. It has central air-conditioning and heating. The whole place is wired for surround sound. Admittedly, it contains only fifty-five square feet of living space. But you can’t beat the open floor plan.

Just after we pass into South Carolina, I catch Radar yawning and insist upon a driver switch. I like driving, anyway — this vehicle may be a minivan, but it’s myminivan. Radar scoots out of his seat and into the first bedroom, while I grab the steering wheel and hold it steady, quickly stepping over the kitchen and into the driver’s seat.

Traveling, I am finding, teaches you a lot of things about yourself. For instance, I never thought myself to be the kind of person who pees into a mostly empty bottle of Bluefin energy drink while driving through South Carolina at seventy-seven miles per hour — but in fact I am that kind of person. Also, I never previously knew that if you mix a lot of pee with a little Bluefin energy drink, the result is this amazing incandescent turquoise color. It looks so pretty that I want to put the cap on the bottle and leave it in the cup holder so Lacey and Ben can see it when they wake up.

But Radar feels differently. “If you don’t throw that shit out the window right now, I’m ending our eleven-year friendship,” he says.

“It’s not shit,” I say. “It’s pee.”

“Out,” he says. And so I litter. In the side-view mirror, I can see the bottle hit the asphalt and burst open like a water balloon. Radar sees it, too.

“Oh, my God,” Radar says. “I hope that’s like one of those traumatic events that is so damaging to my psyche that I just forget it ever happened.”

I never previously knew that it is possible to become tired of eating GoFast nutrition bars. But it ispossible. I’m only two bites into my fourth of the day when my stomach turns. I pull open the center console and stick it back inside. We refer to this part of the kitchen as the pantry.

“I wish we had some apples,” Radar said. “God, wouldn’t an apple taste good right now?”

I sigh. Stupid fourth food group. Also, even though I stopped drinking Bluefin a few hours ago, I still feel exceedingly twitchy.

“I still feel kinda twitchy,” I say.

“Yeah,” Radar says. “I can’t stop tapping my fingers.” I look down. He is drumming his fingers silently against his knees. “I mean,” he says, “I actually cannot stop.”

“Okay, yeah I’m not tired, so we’ll stay up till four and then we’ll get them up and we’ll sleep till eight.”

“Okay,” he says. There is a pause. The road has emptied out now; there is only me and the semitrucks, and I feel like my brain is processing information at eleven thousand times its usual pace, and it occurs to me that what I’m doing is very easy, that driving on the interstate is the easiest and most pleasant thing in the world: all I have to do is stay in between the lines and make sure that no one is too close to me and I am not too close to anyone and keep leaving. Maybe it felt like this for her, too, but I could never feel like this alone.

Radar breaks the silence. “Well, if we’re not going to sleep until four. .”

I finish his sentence. “Yeah, then we should probably just open another bottle of Bluefin.”

And so we do.

It is time for our second stop. It is 12:13 in the morning. My fingers do not feel like they are made of fingers; they feel like they are made of motion. I am tickling the steering wheel as I drive.

After Radar finds the nearest BP on his handheld, we decide to wake up Lacey and Ben.

I say, “Hey, guys, we’re about to stop.” No reaction.

Radar turns around and puts a hand on Lacey’s shoulder.

“Lace, time to get up.” Nothing.

I turn on the radio. I find an oldies station. It’s the Beatles. The song is “Good Morning.” I turn it up some. No response. So Radar turns it up more. And then more. And then the chorus comes, and he starts singing along. And then I start singing along. I think it is finally my atonal screeching that awakes them.

“MAKE IT STOP!” Ben shouts. We turn down the music.

“Ben, we’re stopping. Do you have to pee?”

He pauses, and there’s a kerfuffle in the darkness back there, and I wonder if he has some physical strategy for checking the fullness of his bladder. “I think I’m okay, actually,” he says.

“Okay, then you’re on gas.”

“As the only boy who has not yet peed inside this car, I call first bathroom,” says Radar.

“Shhh,” mumbles Lacey. “Shhh. Everybody stop talking.”

“Lacey, you have to get up and pee,” Radar says. “We’re stopping.”

“You can buy apples,” I tell her.

“Apples,” she mumbles happily in a cute little girl voice. “I likey the apples.”

“And then after that you get to drive,” Radar says. “So you really gotta wake up.”

She sits up, and in her regular Lacey voice, she says, “I don’t so much likey that.”

We take the exit and it’s.9 miles to the BP, which doesn’t seem like much but Radar says that it’s probably going to cost us four minutes, and the South Carolina traffic hurt us, so it could be real trouble with the construction Radar says is an hour ahead of us. But I am not allowed to worry. Lacey and Ben have now shaken off their sleep well enough to line up together by the sliding door, just like last time, and when we come to a stop in front of the pump, everybody flies out, and I flip the keys to Ben, who catches them in midair.

As Radar and I walk briskly past the white man behind the counter, Radar stops when he notices the guy is staring. “Yes,” Radar says without embarrassment. “I’m wearing a HERITAGE NOT HATE shirt over my graduation gown,” he says. “By the way, do you sell pants here?”

The guy looks nonplussed. “We got some camo pants over by the motor oil.”

“Excellent,” Radar says. And then he turns to me and says, “Be a dear and pick me out some camo pants. And maybe a better T-shirt?”

“Done and done,” I answer. Camo pants, it turns out, do not come in regular numbered sizes. They come in medium and large. I grab a pair of medium pants, and then a large pink T-shirt that reads WORLD’S BEST GRANDMA. I also grab three bottles of Bluefin.

I hand everything to Lacey when she comes out of the bathroom and then walk into the girls’ room, since Radar is still in the guys’. I don’t know that I’ve ever been inside a girls’ bathroom in a gas station before.

Differences:

No condom machine

Less graffiti

No urinal

The smell is more or less the same, which is rather disappointing.

When I come out, Lacey is paying and Ben is honking the horn, and after a moment of confusion, I jog toward the car.

“We lost a minute,” Ben says from the passenger seat. Lacey is turning onto the road that will take us back to the interstate.

“Sorry,” Radar answers from the back, where he is sitting next to me, wiggling into his new camo pants beneath his robe. “On the upside, I got pants. And a new T-shirt. Where’s the shirt, Q?” Lacey hands it to him. “Very funny.” He pulls off the robe and replaces it with the grandma shirt while Ben complains that no one got himany pants. His ass itches, he says. And on second thought, he kind of does need to pee.
