Diving the Cenotes of Mexico
Spent a day scuba diving a couple of cenotes south of Playa del Carmen, north of Tulum. The two cenotes were the Ponderosa (also called Eden) and the Tajma-ha (or Taj Mahal). Both great experiences, though not great for still photography unless you want to use a flash all the time (and that sort of defeats the experience and irritates everyone else, so no flash). Definitely better translation with video.
