Took almost the whole course years ago in Jamaica, but ran out of time and money for the certification. Then I started flying... $$

But I will eventually get my card... I've always enjoyed snorkeling, and SCUBA is like snorkeling cubed... the first time I went down the anchor line and kneeled on the bottom, looking up thru 30 feet of water as I took a breath.... it's fantastic!!
I'll probably get my cert.next time I visit Florida.
Last time I was down there, went with a friend and his brother and their girlfriends to Crystal River to swim with the manatee; the brother's an instructor, and just happened to have extra tank, etc. with him, so I rented a BC and he took me down to the mouth of the spring for a brief lesson.
After we came up, they went down into the caves... and saw a couple of 6-ft tarpon hanging around the mouth- wish I'd seen that!!
But just snorkeling around with the manatee was good enough for me... you done that yet?
