Journey to the West 2: A Virtual Overland Tour from Texas to California

This is the auditorium at Carlsbad National Park. At dusk, they have a bat show, and thousands of Mexican free-tailed bats come barreling out of the cave entrance. Most of them head off to the right, far away from the seating area. Here is some park information about the bats.

I think there's a bat in the hole in the center of the photo.

On the left is a real bat. On the right is a cave painting of a bat.
