My husband and I would like to drive from Washington, DC "to and around" New Mexico (Native American sites), Arizona (Grand Canyon), Colorado, stopping in Steamboat Springs, CO to meet up with family. If time allows we would take a side trip from Steamboat for 4 days or so (with a 6 year old) and then start home going through the Badlands. We have about one month to do this starting in late May. From DC to this area we probably want to drive no more than about 6-7 hours per day and would like to make stops but don't know what to see (yet). Our focus this whole way will be on nature, national parks, and culture-not so much on cities. I am beginning to think this is complicated to plan. Is it better to drive highways to make good time and then stop and explore at a few points? I am concerned that a month is not enough to enjoy the southwest, see family and return through the Badlands. Are there guides that suggest times to get from a-b, perhaps suggesting a few side trips, and how much time to allow to see a specific area? Thanks.
