I love snorkeling and have been to some amazing reefs in the Caribbean and Central America. But one time I took a tour boat out to a reef a couple miles off Belize and, unbeknownst to me, one of the attractions of this tour was to go to a place where there are tons of Nurse Sharks, which supposedly don’t attack humans, and you can watch the tour diver feed the sharks and can jump in and swim with the sharks. What could possibly go wrong in this scenario?! Thanks but no thanks!
