I had no idea how long we have been diving. Do you? It was crude and there had to of been lots of issues but people have been diving for over $&@ years. You have to go to find out and you will be amazed. I had no idea this place existed until I was on a dive trip to Florida and saw the sign as I drove by. I had to stop and I was shocked. It is very, very well done with professional displays representing the timeline of human diving.... And it is amazing what we have done getting to our safe, modern equipment. You have to go here if you are in the keys and love diving.
