Another source is as you go into a state, get their campground guides. I know Colorado does a nice job with their state parks and listing lengths. And the national forest offices also have info on their specific forests if you're going to boondock or use their rustic campgrounds. These are a great deal. Usually you will pay about $10 at a rustic site for the priveledge of a fire ring, gravel site and pit toilet. If you want to boondock, you can pull offroad in most forests/grasslands (subject to regulations) and camp for free. We've found some very nice free campsites out west. Not as easy in the midwest. Plus, in the summertime it gets pretty cool at night in the mountains making the need for A/C a non-issue.
