Western slope of Colorado, even southwestern CO might be good, Four Corners area; also parts of Nevada,ner Mesquite (maybe) heck we're only a few hours from *gasp* Vegas! If you do WY, esp. Bridger-Teton, it'd have to be mid-summer for easy-weather access.:-) Idaho hight be a fairly half-way point for many of us, from west coast to mid-Rockies. I'll have to think on it some more. For me, it would depend on whether Rog could take the time off, too.
