Actually, these bats are anything but freewheeling. As 20 million of them emerge from Bracken Caven each spring and summer evening, they fly out in a very orderly fashion (in a spiral "vortex") with all bats flying in the same direction. The alternative is smacking into each other and falling to the ground where flesh-eating beetles, snakes, and other critters await.
