We are planning a long 4th of July weekend to Tampa. I am interested in diving the Rainbow River drift dive (read on a website how relaxing it is!) But the rest of my scuba family (4 males) keep assuring me this would be dull) I guess they think this would be too tame, I also would like to do Crystal Springs dive (and maybe dive with a manatee) I thought that maybe we could do Crystal Springs and Rainbow on one day and the Blackthorn or Sheridan on day 2. Thanks for any and all input!!!
