Less than an hour later, a group of workers in bright orange Gunderson Corporation Jym suits waddled out from Low Dome on their regular duty schedule. Heading for the sea-going equivalent of tractors and combines, nine of the suits carried the regulation two tanks of compressed air on their backs. But one of the group carried the unusual number of three. As the group chatted with each other over their short-range Gertrudes, one suit went casually off by itself into the tall deep weed beds. A moment later, there was a brief flurry of motion as something small and metallic streaked away over the lush farmland, moving toward the distant mountains at an incredible velocity. When the Jym suit returned, it was carrying only two tanks of air.
