Take the California coast down and then hit I-40 across the Mojave and come
up to Flagstaff. You could head to the Grand Canyon and then head into south
east Utah. If you go to Utah and your into Anasazi ruins Grand Gulch
Primitive area is a must hike/campout see. Nights will be cold. Days will
feel warm in the sun. Maybe you'll get lucky and have some rain and get
early spring wild flowers.  I am so jealous. If you do make it to the four
corners area I highly recommend south east Utah. It will not disappoint.
Did I tell you how jealous I was.  Have fun. If you need anymore info pmail
me.  Merv.
