SWIMMING WITH SHARKS
Nope, this not figurative, (e.g. a reference to trial lawyers) but REALLY swimming with some big sharks. Though yours truely has had his share of being chased by hammerheads, smacked by a great whites while poking out from a shark cage, feeding nurse sharks, etc., nothing beats swimming with the gentle Whale Shark (Tiburon Ballenas) off the coast of NE Yucatan.
For a mere $80, you can get on a small boat from Isla Holbox (pron: /ol-bosh/), motor for an hour or so, and find a number of these gentle giants plankton feeding near the surface. This is a yearly phenomenon (June - August) recently discovered by the tourist industry; luckly, the Mexican authorities have had the sense to put these sharks on a special protection program.
