Bracken Cave

This is a picture of the Bracken Cave tour group getting some last-minute bat info from some BCI speakers while waiting for it to get dark enough for the bats to come out. The cave sinkhole is just to the left. Photo taken with a Canon Elan IIe camera on a Manfrotto Wilderness tripod with a 50mm f/1.8 lens, Kodak Royal Gold 100 film.
