A West Virginia caving experience: Caves are the homes to bats. So if you go into a cave during the daytime and shine your light up at the ceiling of the entrance chamber you will see thousands of bats clinging to the ceiling. They are sleeping. Nowadays many of the bat caves in West Virginia are closed to cavers in order to protect the bats. But in the "old days", 25-30 years ago, they were open. On one trip my group of five got a bit delayed inside the cave (one guy had brought a special 3-D camera and tripod along with him and got some really spectacular photographs) so we ended up coming out just at twilight. And as we navigated a long, dry walking passage towards the entrance, the bats awoke. Now this was a large, wide, high dry passage. We should have been able to walk out three abreast. Within about two minutes there were thousands of bats flying around inside the passage - along with us! Thankfully we all had helmets and proper long sleeved clothing on, so we hit the deck and crawled out of that cave on all fours with bats screeching and flying out of the cave above us. Never again did we ever attempt a cave exit at that time of day!
