There is an opportunity for this fail yet, but I'm still planning on making it happen somehow: Annual camping weekend in Ohio. Fly into Columbus with bike, bike to campground ( about 60 miles up the Ohio to Erie Trail) and spend a long weekend camping with friends and family. Then back on the Ohio to Erie trail for two days to get to Cleveland. Catch the train to Pittsburg (Roll on bike service, so I won't even have to box the bike). Take the Great Allegheny Passage and the C&O Canal trails to Washington, DC over the course of about a week. Train home from DC.
