If you've any suggestions for other things I should do on my trip, please offer them. Things to see or do shouldn't cost very much if any money, and I'm mostly interested in nature rather than city things and tourist traps. I am interested in friends, though. Especially friends who wouldn't mind putting me up for the night in a quiet out of the way place; I can take this trip because I don't have a job, but that also means I want to keep expenses down.
The exact length and timing of the trip is yet to be decided, but it will depend on what I figure out to do on the trip before I leave. Until my itinerary starts to become better defined, pretty much any destination that's south and east of Champaign and still in the continental US could possibly be included. The hard limits are that I'm not leaving before Monday, July 18, and I want to be back by Saturday, August 13. I'm not planning on being gone all that time, but I would consider it if I can line up things worth doing to fill the time.
