We had traveled from Glenwood Springs, CO to the KOA in Colorado Springs with a stop at the truck wash in Denver to clean up after the snow we had driven in leading up to Vail. No chance of snow the following day and it was sunny and clear. The next morning we woke up to snow. We had to travel and the forecast said it was just about over and there was nothing expected S. of CO. Springs. Well, we drove for the next few hours in a terrible storm which coated the coach and the toad in a slurry of ice. Our white van was a solid block of black ice and the bottom half of the coach, including 1/2 of the engine radiator, was ice as well. We spent the night in a WalMart as there was no chance we were going to try to make the upcoming mountain grade. We are glad we quit fairly early as the parking lot became loaded with RVer and truckers very quickly!
