Sparkleberry Landing which, I think, is closest to Rimini. I really wish I'd done more research before striking out but it was kind of a spur-of-the-moment trip, the canoe was still on the car from Allegheny Islands (just looks good up there) and the swamp was worth paddling. I'll definitely have to do it again when I have a few days to explore it.
I'm doing additional research now & planning on adding to the TR in case anyone else would care to go.
