My first cave was the best in the U.S., if not THE best in the world (although not exactly unexplored)- Carlsbad Caverns. After getting married, my husband introduced me to “real” caving, which he had been doing for awhile before. Whether you go for the big and beautiful ones, or inch your way along the tiny passages of a little known hole in the ground, you’re bound to have some fun and feel at least a little tinge of spirituality.
