Idaho Never had any desire to dive a cavern. Talked to a guy in Coz a few years back who dove a Cenote (obviously into diving, said he'd done 26 dives in 10 days). Took the ferry over to the mainland, rode in a van, had to hike a half mile back in the jungle carrying his gear and wearing his wet suit. 90 degrees, and there ain't no breeze. But then he got to jump into a cold pond topped with scum to see a few little fish in limited viz. Sounds like fun to me.
Things that really suck.
