Tony, I haven't taken the 5er through there heading west, but east bound is a piece of cake. Going West, it's quite a long steep pull up the hill, but you'll be able to make it. The Glenwood Canyon it beautiful & awe inspiring. Also Doc Holliday is buried in Glenwood Springs, they just don't know exactly where in the cemetery!!! If you are taking I-70 on to CA, stop in Palisade, CO, just E. of Grand Junction they have some AWESOME peaches. There is a stand just off the interstate where we've bought them. Also they have some awesome peach salsa.
