I have ridden across the US twice on a bicycle, 3 times in a plane , 6 or 7 times in a car and hitchhiked once. The only thing left is a by foot, on a boat (which I haven't finished yet) and on a moped,
Last summer I met a couple who rode thier 50 cc mopeds from Burbank Ca. to Boston Ma. they spent 62 days on thier mopeds meandering thier way across the country. they camped nearly every night and had a great time. I could see myself doing that.
check out thiis moped touring group , gotta love the trailer
