Chicago>Denver>Glenwod Springs>Bryce Canyn>Tucson. November

ice2fire - I 70 has very long grades up and down. Going west from Denver there is a many mile long steep to very steep grade to the Eisenhower Tunnel. Then a big downhill on the other side. And many other long ups and downs. And these are at higher than usual elevations. The Eisenhower is over 11,000 ft high.

This is easy in a good car in good weather. It is hard on any RV. I have done it, but do not consider it fun at all.
