Im in the middle of planning a drive across the States next year but have yet to decide on how to get from Monument Valley to Yellowstone. I would like to stop off somewhere between the two places and do a bit of sightseeing or some watersports if possible. I was considering either Salt Lake City, Vernal or the Flaming Gorge area. Can anybody advise me please? I have to admit that Salt Lake City hasnt inspired me yet in any vacation brochure ive read, but is it worth a day of my time to explore?
