I just came back from the Hill Country in Texas and I really liked riding the hills, going up and down. I started to think about some of the roads that I would have liked to go on, but they didn't have shoulders. I was wondering how you planned your trips, or you just don't worry about it. I was thinking how steep some of the hills were, if a car was coming over them it wouldn't give them much of a chance to move over if you were just over the apex of the hill. I find myself looking at shoulders as I'm driving around, wondering how safe it would be for riding.
