I did some snorkling in Looe Key in Key West, awesome time, even if I did have trouble getting the whole equalizing thing. Saw some barracuda (
here's a pic). My wife and I stayed in a beachfront house with a long pier outside, and every day we'd go out to the end of the pier and hang out for a bit. Well, every day there were huge barracuda hovering at the surface of the water, and one day a huge nurse shark swam by. I really want to go again.
With this year's tax return, I am going to get certified in SCUBA and hopefully get a volunteer position at the Baltimore Aquarium. Then I'll get to feed sharks and rays all the time!
