Free Fifty Degrees Below by Kim Stanley Robinson Page A

that, sat down and lost ten dollars to the boy, playing the best he could but confirming his impression that he was seriously outclassed. He said little, left as soon as it seemed okay.
    The first time he climbed his candidate chestnut oak he had to use crampons, ice axe, and a telephone lineman’s pole-climbing kit that he had from his window-washing days, dug out of the depths of his storage locker. Up the tree at dawn, kicking in like a telephone lineman, slinging up the strap and leaning back in his harness, up and up, through the scrawny understory and into the fork of the first two big branches. It was nice to be able to sink an ice axe in anywhere one liked; an awkward climb, nevertheless. It would be good to confirm a tree and install a ladder.
    Up here he saw that one major branch curved out over the creek, then divided into two. That fork would provide a foundation, and somewhat block the view from below. He only needed a platform a bit bigger than his sleeping bag, something like a ledge bivouac on a wall climb. There was a grand view of the ravine wall opposite him, green to a height considerably higher than he was. Glimpses of the burbling creek downstream, but no view of the ground directly below. It looked good.
    After that he parked and slept in the residential neighborhood to the west, and got up before dawn and hiked into the forest carrying lumber and climbing gear. This was pretty conspicuous, but at that time of day the gray neighborhood and park were completely deserted. It was only a ten-minute hike in any case, a drop through forest that would usually be empty even at the busiest time of a Sunday afternoon.
    He only needed two dawn patrols to install a climbing ladder, wound on an electric winch that he reeled up and down using a garage-door remote he found at Radio Shack. After that the two-by-sixes, the two-by-fours, and two three-by-five sheets of half-inch plywood could be hauled up using the ladder as a winch cable. Climb the ladder with the miscellaneous stuff, ice axing into the trunk for balance, backpack full of hardware and tools.
    Collar around trunk; beams on branches; plywood floor; low railing, gapped for the ladder. He maneuvered slowly around the trunk as he worked, slung in a self-belay from a piton nailed above him. Cirque du Soleil meets Home Improvement. Using woodscrews rather than nails reduced the sound of construction, while also making the thing stronger.
    Every day an hour’s work in the green horizontal light, and all too soon it was finished, and then furnished. A clear plastic tarp stapled and glued to the trunk overhead served as a see-through roof, tied out to branches on a slant to let the rain run off. The opening in the rail, the winch screwed down to the plywood just inside it. Duffel bag against the trunk holding rolled foam mattress, sleeping bag, pillow, lantern, gear.
    Standing on the platform without his sling one morning, in the slanting light that told him it was time to drive to work, he saw that the thing was built. Too bad! He would have liked the project to have lasted longer.
    Driving across town that morning, he thought, Now I have two bedrooms, in a modular home distributed throughout the city. One bedroom was mobile, the other in a tree. How cool was that? How perfectly rational and sane?
             
    Over in Arlington he drove to the NSF basement parking lot, then walked over to Optimodal Health Club to shower.
    Big, new, clean, blazingly well-lit; it was a shocking contrast to the dawn forest, and he always changed at his locker feeling a bit stunned. Then it was off to the weight room.
    His favorite there was a pull-down bar that gave his lats a workout they otherwise would not get. Low weight, high reps, the pull like something between swimming and climbing. A peaceful warm-up, on his knees as if praying.
    Then over to the leg press. Here too he was a low-weight high-rep kind of guy, although since joining the club it had occurred to him
