one more thing Kerensky... Just in case you're new to I-70, try to time it so that you're crossing over the Rockies during daylight hours. The scenery is incredible. My favorite stretch is Glenwood Canyon, just east of Glenwood Springs, CO... The Interstate is actually perched on "shelves" hanging from the sides of the canyon walls... absolutely beautiful...

Eastern Colorado and Kansas are boring as hell. You won't miss anything if you drive them at night...
