I think the forest in Crawfordville, Fl. would be our best bet. The river fluctuates so much with the spring showers that I'd hate for everyone to come from all around only for the springs to be backed up. The forest atleast offers a good solid day of riding with mixed terrain. No rocks really, but a mix of mud, sand, roots and stuff. I enjoy riding over there. It's not really all that fun unless you go with a crew of atleast 3. There is a good bit of acreage there. It's not hard for every tree to look the same. You get in some of those pine stands in that place, you feel like an ant.
I'm down for whatever ya'll want to do though... I wish I could take you all to the Alapaha but its fluctuation level is much harder to judge. Hopefully @Average_Joe will chime in with his thoughts. He's basically knows all of the places I ride and his insight will help.
