I was going to Escalante, but right now the plan for me is to be camping in Bell & Little Wild Horse this weekend, which is a nice hike, but I might try some of the scenic road stops if time permits.
I just picked up Steve Allen's Canyoneering the San Rafael Swell and Michael Kesley's Hiking and Exploring Utah's San Rafael Swell on the advice of my cousin. When I have the time, I will look for information on the Sinbad area. The only think I recall seeing on a quick glance were just markings on the map for the Heart of Sinbad road and the Head of Sinbad off I-70, not too far from the Swasey cabin.
Good luck this weekend!
