Deep deep deep underground lie the Carlsbad Caverns. Stalagmites and stalactites intersect majestic cave halls and offer a refreshing cool contrast to the pressuring heat of Texas. And where there are caves, there are bats. The up to a million bats emerging simultaneously from a cave opening at sunset is supposedly a remarkable sight. I had half expected to see something similar to the smoke monster in Lost, but no such effect was to be found. Big ouverture, small show.
