Hey postcard travelers....don't forget your sweater on this trip. Says it stays at a constant 56degrees F. within the caverns.
Check out the back cover. The minibooklet says the bats fly out from the caverns each evening from April through October to feed in the valleys of the Black and Pecos Rivers below. Wow! I have added this place to our Bucket List!!!
