Hitch hiking is no big deal. With a bike, and being an older man (making assumptions because we are on bike forums) it is harder of course. I am young and hitchiked a little over then summer on the east coast. It sucks, takes a long time even if your friendly, and we did get picked up by a cop, he drove us to a better hitching spot though so that was nicer than Id think.
-Good luck, live life on the wild side
