And we'd always had a roving foot, both of us.

No, we had decided together to come to Mars--the way we decided together on everything. Now she was turning against me.

* * * * *

I tried to jolly her. "Buck up, kid," I said. I didn't dare turn up her oxy pressure any higher, but it was obvious she couldn't keep going. She was almost sleep-walking now.

We pressed on over the barren terrain. The geiger kept up a fairly steady click-pattern, but never broke into that sudden explosive tumult that meant we had found pay-dirt. I started to feel tired myself, terribly tired. I longed to lie down on the soft, spongy Martian sand and bury myself.

I looked at Val. She was dragging along with her eyes half-shut. I felt almost guilty for having dragged her out to Mars, until I recalled that I hadn't. In fact, she had come up with the idea before I did. I wished there was some way of turning the weary, bedraggled girl at my side back into the Val who had so enthusiastically suggested we join the Geigs.

Twelve steps later, I decided this was about as far as we could go.

I stopped, slipped out of the geiger harness, and lowered myself ponderously to the ground. "What'samatter, Ron?" Val asked sleepily. "Something wrong?"

"No, baby," I said, putting out a hand and taking hers. "I think we ought to rest a little before we go any further. It's been a long, hard day."

It didn't take much to persuade her. She slid down beside me, curled up, and in a moment she was fast asleep, sprawled out on the sands.

_Poor kid_, I thought. Maybe we shouldn't have come to Mars after all. But, I reminded myself, _someone_ had to do the job.

A second thought appeared, but I squelched it:

Why the hell me?

I looked down at Valerie's sleeping form, and thought of our warm, comfortable little home on Earth. It wasn't much, but people in love don't need very fancy surroundings.

I watched her, sleeping peacefully, a wayward lock of her soft blonde hair trailing down over one eyebrow, and it seemed hard to believe that we'd exchanged Earth and all it held for us for the raw, untamed struggle that was Mars. But I knew I'd do it again, if I had the chance. It's because we wanted to keep what we had. Heroes? Hell, no. We just liked our comforts, and wanted to keep them. Which took a little work.

_Time to get moving._ But then Val stirred and rolled over in her sleep, and I didn't have the heart to wake her. I sat there, holding her, staring out over the desert, watching the wind whip the sand up into weird shapes.

The Geig Corps preferred married couples, working in teams. That's what had finally decided it for us--we were a good team. We had no ties on Earth that couldn't be broken without much difficulty. So we volunteered.

_And here we are._ Heroes. The wind blasted a mass of sand into my face, and I felt it tinkle against the oxymask.

I glanced at the suit-chronometer. Getting late. I decided once again to wake Val.
