If it were in Colorado, I'd definitely make it. Heck, I'd go to Yellowstone too, but hey. There are some roads I've always wanted to get onto in Colorado that I've not done yet, would be a very good chance to change that.

Toss my vote in for Colorado as well. I don't have much knowledge of the area though, so planning is up to others. Then again, SLC was mentioned and I've always wanted to get up there too.
