In the old days, you could break out you Rand McNally or you AAA maps and plan a trip. Obviously, this is still an option.
Years ago I had a Microsoft application, Trips and Streets, that was a pretty good tool.
Now although I have Google maps on my iPad, it is really not much of a planning tool. I guess I'm looking for an app that lets me start with a map of the US, decide where I want to go, then zero in on areas for more detailed route planning.
