My friend Jane was on the Congress Bridge one time at dusk and overheard two sorority girls talking about the bats.

“I read somewhere that there’s a BILLION bats here,” said one. “Wow, that’s a lot,” said the other.

I’m trying to convince my friend Mike to name his new band “One Billion Bats”- so I made this poster. It’s modified from this flickr photo and uses the font Gotham.
