Guess I’m going to have to try Manatee springs next, maybe before the cruise. I have dove Ginnie and really enjoyed diving in the river, but it was a battle trying to get back to the opening where we started. Oh did I mention we’re new...LOL The current at the end of the river run was unbelievable. At one point I went down to the bottom because the "current is not that bad under water" (yeah right) and as much as I kicked I didn’t move, so we surfaces and pretty much kicked until we made it back to the opening. It was fun dive though.
