As someone who has toured by herself I say that it isn't all that different from riding in your own neighborhood. You just don't turn around and head home halfway through the day.
I rode from southern Minnesota to Sioux City Iowa - didn't quite make it back to Lincoln, NE - by myself and had a gas. I did take a cell phone and checked in with DH every night, but that was as much to keep him from worrying as anything else.
Anyway, even though I wasn't on an "official" bike route, I never felt unsafe. I even had the feeling that the local truckers were watching out for me. No, safety was not one of the concerns. Hypothermia, on the other hand...
As the commercial says, Just Do It. You tend to regret the things in life you didn't do.

Give big space to the festive dog that make sport in the roadway. Avoid entanglement with your wheel spoke.
