Mae said, “And footprints.”
     “What? You uggs discount mean our footprints? From us walking over here? Shit, Mae, the sand’s been blowing for the last fifteen minutes. There’s no footprints left to find.” We watched the swarm hang there, rising and falling like it was breathing. The cloud had turned mostly black now, with just an occasional glint of silver. It had remained at the same spot for ten or fifteen seconds, pulsing up and down. The other swarms were continuing in their zigzag course, uggs discount but this one stayed where it was.
     Charley bit his lip. “You really think it sees something?”
     “I don’t know,” I said. “Maybe.”
     Suddenly, the swarm rose up, and began to move again. But it wasn’t coming toward us. Instead, it moved on a diagonal over the desert, heading back toward the door in the power building. When it came to the door, it stopped, and swirled in place. “What the hell?” Charley said.
     I knew discount uggs for women what it was. So did Mae. “It just tracked us,” she said. “Backward.” The swarm had followed the path we had originally taken from the door to the rabbit. The question was, what would it do next?
     The next five minutes were tense. The swarm retraced its path, going back to the rabbit. It swirled around the rabbit for a while, moving in slow semicircles back and forth. Then once again it retraced ugg boots discount outlet the route back to the power station door. It stayed at the door for a while, then returned to the rabbit.
     The swarm repeated this sequence three times. Meanwhile, the other swarms had continued their zigzagging around the building, and were now out of sight. The solitary swarm returned to the door, then headed back to the rabbit again.
     “It’s stuck in a loop,” Charley said. “It just does the same thing over and cheap uggs online over again.”
     “Lucky for us,” I said. I was waiting to see if the swarm would modify its behavior. So far it hadn’t. And if it had very little memory, then it might be like an Alzheimer’s patient, unable to remember it had done all this before.
     Now it was going around the rabbit, moving in semicircles.
     “Definitely stuck in a loop,” Charley said.
