I have to agree with what has been said. I don't think we need to replicate the car camping group hang of Ocala every time we get together. That is a hard expectation to reach. By focusing on a hiking/backpacking or a paddling weekend, we could have more frequent get togethers and have more flexibility when it comes to campsites.
If we are tentatively looking at the second weekend of April, let say, we could have a recon trip to Hog Island, Silver Lake, or where ever in late February to see the areas first hand.
The real trick is to find a suitable hiking area that is treed for hanging, maybe some water for drinking, and a pleasant walk.
I don not know the area too well, but Potts Preserve has a 16 mile loop trail and primitive campsites. Here is some information from the SWFWMD site.
