Nice work, Salty! I knew I had seen terrain like that, but couldn't quite place it. I scanned all around Grand Canyon for an end-of-road overlook like that, even checked Grand Canyon West. No luck, gave up.

But those cliffs are so much like those around Moab, and I've mountain biked the Slick Rock trail. But then I didn't go looking for an overlook.

Now how does the clue, "Where cowboys corral mustangs and (66) Thunderbirds fly." fit in? I'm the clueless type.
