I don't any more, but used to- a lot. Absolutely loved it and once you get used to the equipment (and some regulators/mouthpieces are definitely better than others) it is so relaxing. I hated for the dives to end!Do you scuba Friday? I tried to learn that once but couldn't take the claustrophobic/I can't breath feeling. Now snorkeling...that's fun! The Great Barrier Reef would be amazing.
Snorkeling now seems like so much more work to me - and you can only stay down for a minute at a time, instead of half an hour!
