Hey, just got back from the Keys & had a good time.  

This trip was mostly for relaxation, but one of the highlights was a 4 hour kayak trip with the wife & kids.  In calm backwater areas we saw sharks, rays, sea turtle, barracuda, snakes and the ever present huge schools of tiny fish plus some bigger ones;  don't know what kinds any were.

We did go out in the ocean proper to fish and snorkel.  Snorkelling is like swimming in a fish tank with big barracuda. Kids caught colorful fish on a reef that looked like they should be in an aquarium.  Very fun!
