I'm down for the Grand Canyon or South Tahoe. Some amazing driving roads in those parts (from what I hear) Plus, neither one (to my knowledge) is a terrible drive for the following
Western CO (earl??)
any of AZ (myself, Dayle, flagstaff SVX, and a few others from AZ)
Albuquerque (SVXtacy, yoda3000)
SLC (lots of folks)
West Yellowstone seems cool, but from my (limited) knowledge of where people are located, it seems out of the way.
And for good measure, I'm gonna use a few more parenthesis ()
