Craig, I'd love to get down there and run it, I've been wanting to do that trail for a long time (as well as Chimney Rock, which I think is just northeast of there). I won't be able to make that weekend but I hope to get down there eventually. I've actually been wanting to explore the Ironwood National Monument area also when it gets cooler... you might be interested in that since it's only 30 miles north of Tucson.
So don't get discouraged... we've had trips completely fall apart and ones where there was only 1 or 2 people. I hope others can join with you and make it a go because I know it's a nice area. Good Luck and Have Fun!
