We have a lot of paved county roads around here, and I ride alone on them all the time. It's pretty wide open though, not twisty, and not many trees. I carry a cell phone and ID, along with plenty of water. Had a bit of a concern a couple of months ago when one car was passing another on a hill, and I was forced to bail into the ditch. Hopefully though if there had been a collision, one of the drivers would have stopped to help.
