I'm planning on doing some WWOOFing this summer and rather than drive/take train/fly, I was thinking about using it as an excuse to take a nice long walk. I'm no stranger to long hikes (I worked Trails for the Park Service), but I've never backpacked outside of Parks/Forest Service/BLM lands. So I come to you looking to predict problems. I'm starting out in Florida and will end up in NC, TN, or KY. The idea is to have at least thought about most contingencies before i hit the road. Thanks!
