Ahh, but if you are at Canyonlands, its only a hop and skip down to
Mexican Hat and Monument Valley, maybe with a side trip to Canyon de
Chelly. Then, of course, the Grand Canyon (North Rim) is just down the
pike a way....which puts you just within arms length of Kodachrome
Basin and Bryce Canyon. Then, only a small detour puts you within a
day's journey of Yosemite, then on up the Pacific Crest to see the
Redwoods....and then its just a small trip to Mt St Helens....then the
Columbia River Gorge...Craters of the Moon....down into the Clave from
the north....

Yep, a month or so might be just about right.
