Herd mentality: Goats munch their way along BART property to help district prevent fires

BART is employing goats to reduce fire risk and cut noise pollution on hillsides along train routes in the Bay Area, continuing a practice that began about five years ago and has created other unintended benefits.

Transit agency officials say the four-legged weed-eaters offer advantages to using lawn mowers and other power tools, which carry higher risk of sparking fires and create air pollution.
