Scientists fleeing border, smugglers

Biologist Karen Krebbs used to study bats in Organ Pipe Cactus National Monument on the Arizona-Mexico border. Then, she got tired of dodging drug smugglers all night. "I use night-vision goggles, and you could see them very clearly" - caravans of men with guns and huge backpacks full of drugs, trudging through the desert, Krebbs said. After her 10th or 11th time hiding in bushes and behind rocks, she abandoned her research.
