Theres also Holy Lands off 27 just north of the WPB county line on the west side. Take the road all the way west till it becomes a dirt road and there are trails along the power lines. With all this rain though I'd be prepared to get stuck. Hopefully you have some lift, beefy tires, good axles, and at the bare minimum a winch. And some friends with 4x4's. It gets sloppy out there during the wet season. But who knows. I'm not sure of anything in Weston and 27 but if you find something out let us know.
