RE: Road Suggestions
Hey marti, If you don't have a GPS, weather permitting, try I-40 West until you get to Flagstaff, AZ. Go North on US 89 through Page, AZ, Kanab, UT on over to I-15 in Utah. You can stop and see the Grand Canyon, just a short side trip off of US 89 North of Flagstaff, AZ. You can take I-15 North all the way to Montana.
An alternate route would be to take I-25 North out of Albuquerque, NM through Denver and on to Montana.
On your way back head down I-15 to Las Vegas, NV and then take US 95 down through Laughlin, NV. From there you can take multiple routes through Arizona.
