Oh, bats are a big tourist attraction around here. They first started roosting under the bridge in the 1980's, right around the time some big hotels were being built along Town Lake. The developers wanted to poison them, but a Mr. Tuttle formed Bat Conservation International and educated the public about the environmental benefit of bats (more plants are pollinated by bats than bees worldwide, and they eat their weight in flying insects every night) Now those same hotels advertise Bat Watching Happy Hours and tour boats.
