Transportation looks doable from Baltimore. SW air ($200) one way to Buffalo. Amtrak to Baltimore, ~$100. No car tour, sweet!
FWIW: I am not opposed to stealth camping, but do like a shower once in awhile. I can always B&B it if necessary. Hostels, hmmm. Used to love them, not certain these days but will check them out. Looks like a plethora of stealth camping just south of the Daks.
Thanks for the ridewithgps map!! Appreciate you sharing with me/us.
