I have a soon to be son-in-law that's from the northern Florida, Suwanee River area. He grew up with guys that recover the lost timber from 100 + years ago from the river. He said the homemade equipment they use is worth the trip to see.
I would love to get some of the wood. It's a 6 hour drive without a trailer so I don't know if the math will work out right for re-sale, but it might be good for my own.
