Jeff,
Thanks for the quad names! That was exactly what I was looking for as I will now download them and do some work with my mapping software.
I spent half a week at Moab a couple of years ago wheelin' with two guys that live near Fresno. They said they ran the Dusy about 4 or 5 times a year with others in their local club. They said I would feel right at home on the trail based on what we were running for Moab trails.
Only one thing bothers me....you said the Rubicon has a little less dust! OH MY!
The one thing I remember so clearly about the Rubicon is that I could stand in the middle of the trail and fart....with the results being nearly "Pig-Pen" (in the Charlie Brown cartoon). I'll never forget just how fine that dust was.
