Just returned yesterday from a 4,150+ mile, 8 state run from Tucson to Yellowstone/Grand Teton NP's. While you probably need reservations at the ultimate destinations winging it along the way has its charm. Find a nice area, just stick around and explore, weather really good or bad... you will almost always have options. On a whim we diverted from our tentative route and went to Cody Wyoming g and had a blast at the Buffalo Bill Wild West Center - a MUST see if you are ver anywhere close.
We left a nice RV park {Riverside} in Provo Utah Tuesday morning planning on ending up at Jacob Lake {north of the North Rim of the GC} but when we got closes the entire mountain was engulfed by the Magnum fire. We reversed course back to Hurricane and ended up in St. George. We had a number of choices and it worked out fine... no harm, no foul.
Stay flexible and go with the flow.
:C
