You will have a great trip.I have been riding this area for years and still find new things.
Restaurants,In Green River just north of where you will be riding and worth the side trip.Raises his own beef and hand cuts his own fries.Great steaks or burgers.
Mexican Hat:can't remember the restaurant's name but there is not much in Mexican Hat.This is the restaurant on the river and has the best Navajo Tacos in the world.
Roads: be sure to go to Natural Bridges and then ride the road from there to Mexican Hat.You will go down the Moqui Dugway.It is steep,and scary looking,but much more scary looking then really scary.The view is magnificent,you will think you have come to the edge of the world and 1 foot farther and you will fall off into nothing.I think you can just about see to Flagstaff.Stop at Edge of the Ceders in Blanding and I could go on and on but you can't time is just always so limited.That of course gives you an excuse to come back.Let me know what days you will be in the area and if I can break away I will join you for a day or so.
