Thanks rodster!
I was reading where Road & Track took a group of H3's through there in 3 hours. It looks like fun. (Definitely do-able.) Located near Florence, AZ, just southeast of Phoenix.
The trail ratings in the link above, gives some of the obstacles 4 and 4+ ratings. One bypass gets rated a 4 also. I noticed there weren't any Hummers in their group.
