Howdy...Planning a cross country trip in early June from my home in Alabama through the Rockies up into B.C. Canada back down the Pacific Coast Hwy then home via Vegas, Grand Canyon, etc. Somewhere around 7k miles and about 3 weeks planned on the road. We'd like to experience nature at it's finest and save a few bucks so camping part of the time is an option we're considering. Does anyone know the rules for pitching your tent in the wide open spaces of Colorado, Montana, New Mexico, etc? Is it OK to arbitrarily pick a non-populated spot that isn't posted and plop down?
