Dear cross-country tourist,
We forumites need more info to help you plan a tour, particularly the season of travel, the amount of vehicle traffic you can tolerate, and if there are any places (friend/family) you want to visit. Some folks, like myself, actually like a lonely route in the desert, with nights under the stars. Others put a higher priority on a cold beer, hot shower, and warm bed. Once we know what you have in mind, we can help with route recommendations in our areas of expertise.
