There was a tree. I remember it. I swear I'd be able to recognize it. Because it looked so unusual.

It stood on my left, in the distance, by Interstate 80. At first, it was just a blur in the shimmering heat haze, but as I drove closer, its skeletal outline became distinct. Skeletal: that's what struck me at first as being strange. After all, in August, even in the sun-parched Nebraska panhandle, trees (the few you see) are thick with leaves, but this one was bare.

So it's dead, I thought. So what? Nothing to frown about. But then I noticed the second thing about it, and I guess I'd subconsciously been reacting before I even realized what its silhouette resembled.

Stronger than resembled.

I felt uneasy. The tree was very menorahlike, a giant counterpart of the candelabrum used on Jewish religious services. Eight candles in a row. Except in this case the candles were barren branches standing straight. I shrugged off an eerie tingle. It's just a freak, an accident of nature, I concluded, although I briefly wondered if someone had pruned the tree to give it that distinctive appearance and in the process had unavoidably killed it.

But coincidence or not, the shape struck me as being uncanny – a religious symbol formed by a sterile tree ironically blessing a drought-wracked western plain. I thought of The Waste Land.

For the past two weeks, I'd been camping with friends in the Wind River mountains of Wyoming. Fishing, exploring, rock-climbing, mostly sitting around our cook fire, drinking, reminiscing. After our long-postponed reunion, our time together had gone too quickly. Again we'd separated, heading our different ways across the country, back to wives and children, jobs and obligations. For me, that meant Iowa City, home, and the University. As much as I wanted to see my family again, I dreaded the prospect of still another fall semester, preparing classes, grading freshmen papers.

Weary from driving (eight hours east since a wrenching emotional farewell breakfast), I glanced from the weird menorah tree and realized I was doing seventy. Slow down, I told myself. You'll end up getting a ticket.

Or killed.

And that's when the engine started shuddering. I drive a secondhand Porsche 912, the kind with four cylinders, from the sixties. I bought it cheap because it needed a lot of body work, but despite its age, it usually works like a charm. The trouble is, I didn't know the carburetors had to be adjusted for the thinner air of higher altitude, so when I'd reached the mountains in Wyoming, the engine had sputtered, the carburetors had overflowed, and I'd rushed to put out a devastating fire on the engine. In Lander, Wyoming, a garage had repaired the damage while I went camping with my friends, but when I'd come back to get it, the accelerator hadn't seemed as responsive as it used to be. All day, the motor had sounded a little noisier than usual, and now as it shuddered, it wasn't just noisy, it was thunderous. Oh, Christ, I thought. The fire must have cracked the engine block. Whatever was wrong, I didn't dare go much farther. The steering wheel was jerking in my hands. Scared, I slowed to thirty. The roar and shudder persisted. I needed to find a mechanic fast.

I said this happened in Nebraska 's panhandle. Imagine the state as a wide rectangle. Cut away the bottom left corner. The remaining top left corner – that's the panhandle, just to the east of Wyoming. It's nothing but broad flat open range. Scrub grass, sagebrush, tumbleweed. The land's as desolate as when the pioneers struggled across it a hundred years ago. A couple more hours into Nebraska, I wouldn't have worried too much. Towns start showing up every twenty miles or so. But heading through the panhandle, I hadn't seen a sign for a town in quite a while. Despite the false security of the four lane Interstate, I might as well have been on the moon.

As a consequence, when I saw the off ramp, I didn't think twice. Thanking whatever god had smiled on me, I struggled with the spastic tremors of the steering wheel and exited, wincing as the engine not only roared but crackled as if bits of metal were breaking off inside and scraping, gouging. There wasn't a sign for a town at this exit, but I knew there had to be a reason for the off ramp. Reaching a stop sign, I glanced right and left along a two lane blacktop but saw no buildings either way. So which direction? I asked myself. On impulse, I chose the left and crossed the bridge above the Interstate, only then realizing I headed toward the menorah tree.

Again I felt that eerie tingle. But the shuddering roar of the engine distracted me. The accelerator heaved beneath my foot, sending spasms up my leg. The car could barely do twenty miles an hour now. I tried to control my nervous breathing, vaguely sensing the tree as I passed it.

On my left. I'm sure of it. I wasn't so preocuppied I wouldn't remember. The tree was on the left of the unmarked two lane road.

I'm positive. I know I'm not wrong.

I drove. And drove. The Porsche seemed ready to fall apart at any moment, jolting, rattling. The road stretched ahead, leading nowhere, seemingly forever. With the menorah tree behind me, nothing relieved the dismal prairie landscape. Any time now, I thought. I'll see some buildings. Just another mile or so – if the car can manage that far.

It did, and another mile after that, but down to fifteen now. My stomach cramped. I had the terrible sense I should have gone the other way along this road. For all I knew, I'd have reached a town in a minute. But now I'd gone so far in this direction I had to keep going. I wasn't sure the car could fight its way back to the Interstate.

When I'd first seen the menorah tree, the clock on my dashboard had shown near five. As I glanced at the clock again, I winced when I saw near six. Christ, just a few more hours of light, and even if I found a garage, the chances were it wouldn't stay open after six. Premonitions squeezed my chest. I should have stayed on the Interstate, I thought. There at least, if the car broke down, I could have flagged down someone going by and asked them to send a tow truck. Here, I hadn't seen any traffic. Visions of a night spent at the side of the road in my disabled car were dismally matched by the wearying prospect of the long hike back to the Interstate. I'd been planning to drive all night in hopes of reaching home in Iowa City by noon tomorrow, but if my luck kept turning sour, I might not get there for at best another day and likely more, supposing the engine was as bad as the roar made it seem. I had to find a phone and tell my wife not to worry when I didn't reach home at the time I'd said I would. My thoughts became more urgent. I had to -

That's when I saw the building. In the distance. Hard to make out, a vague rectangular object, but unmistakably a building, its metal roof reflecting the glint of the lowering sun. Then I saw another building, and another. Trees. Thank God, a town. My heart pounded almost as hard as the engine rattled. I clutched the steering wheel, frantically trying to control it, lurching past a water tower and an empty cattle pen. The buildings became distinct: houses, a car lot, a diner.

And a service station where I lurched to a raw-nerved stop, my hands still shaking from the vibrations of the steering wheel. I shut off the engine, grateful for the sudden quiet, and noticed two men at the pump, their backs to me. Self-conscious about my beard stubble and my sweat-drenched clothes, I got out wearily to ask directions.

They had their backs to me. That should have told me right away that something was wrong. I'd made such a racket pulling up it wasn't normal for them not to turn, curious, wondering what the hell was coming.

But they didn't, and I was too exhausted for my instincts to jangle, warning me. Stiff-legged, I approached them. "Excuse me," I said. "I guess you can tell I've got some trouble. Is the mechanic still on duty?"
