I know how to search a certain location for camping.Lets say I'm leaving Indianapolis and wish to get to Route 66 and go to Oklahoma(central). I wish to never be on interstate but back country highways. How would a person search a specific route when it doesn't matter where you pull up for the night. No walmart or other parking lots is desired. Rest areas and actual camp grounds is what I want. I know it's not a simple request. Thanks to any who takes the time to think about it and answer.
