You live near Ozona? Are you talking about the Caverns of Sonora? I studied those caves, they are the nicest caves in the world. Simply amazing.
Oh by the way, by me there are two caves, one at 6000 feet and its 72F year around, east facing. The other at 4500 feet and west facing and is 82F year around. I was in those caves literally hundreds of times. Found a green rat and a diamondback at the entrance of the west facing cave. Free tailed bats roost just inside.
