If you haven't checked this museum out before you should make a point of it. It is a unique collection of diving apparatus and history close by in the Keys.
They have some interesting events going on in March detailed at:
http://www.divingmuseum.org/wp/?page_id=124
things like; “Commercial Diving In Depth” and “Dive to the Unknown” An Evening with Free Diving World Record Holder Bob Croft.
I met Bob at DEMA aside from hearing about him since I was a teen growing up in Ft. Lauderdale. He made a record free dive off the City in the 1967. If you can buy a copy of the video of the from the 1960's TV program documenting the dive from Bob you should get one.
Anyway, it's a gem and right here on US 1 on the route to great Keys diving and kiting!
