Did you guys travel the Moqui on your way to Hall's Crossing? 10% grade and it was raining if memory serves me right. I saw some video of the roadway with oncoming traffic....that could be a challenge.
Yep - This was my 4th year going to Halls Crossing & every year I've taken the Moki Dugway. Never had an issue. It can be intimidating but if you take your time it's a nice ride. Its similar to Fish Creek Hill in a way.
I think Fish Hawk posted a video last year of some guy driving his semi down it.
