The bats live under Congress Street Bridge in Austin. Tourists stand on top of the bridge. Locals take you to the small park under the bridge! Definitely a better view underneath. You wait for sunset, til the bats are ready to come out from under the bridge to eat. In the meantime, we heard them squeak, made lots of Batman and the Count from Sesame Street jokes. Then they come. They fly out for more than an hour! It’s the largest urban bat population in the world, they say.
