I found this online, uncredited, during a search for something else, and it’s just so cool I had to share it. If you know who the photographer is, or if the rights are owned, please let me know.
By the way, my buddy Tim Brown and I took an evening to see the “bat bridge” in Austin. They’re nothing like the apparent size of this one, but it’s astonishing just how many bats come flying out of there in a seemingly endless stream each night. If you’re ever in Austin, make a chance to check it out.
