CIMG7455 E against Austin skyline
While the ACA'ers were watching the bats come out from under the Congress bridge, E was much more interested in watching the ducks.
On September 22rd, 2007, the members of Atheist Community of Austin went on a now-annual cruise on Town Lake, and watched the bats emerge at dusk from the Congress Avenue bridge.
Here are my pictures from the other bat cruises:
Bat cruise of 2006
Bat cruise of 2008
Bat cruise of 2013, with P. Z. Myers as a special guest.
