There was an old-fashioned building a block away, and the corners of its stepped peak had been carved down to make a kind of mountain, with rocks and grass, and a waterfall that fell and hit rocks and then fell again. It made her smile, why anybody had gone to that trouble. Drifts of steam came off the water, where it hit. It couldn't just fall down into the street, though, she thought, because it would cost too much. She guessed they pumped it back up and used it over, around in a circle.
