Me and some buddies plan on going on a road trip through the western United Sates. Starting from Tulsa, OK. From San Diego all the way up the West Coast stopping in many cities along the way to Seattle then over to Glacier national park, south to salt lake city then east to Vail, Co. We plan to Stay in the cities half of the time and camp the other half. What do we need to know about camping, cool things to do in cities along the way, any warnings, Etc. Anything helps. looking for advice. Thanks
