Here is a challenge for you. Doing 60 "Paved" passes in Colorado in nine days. I have done quite a few but there are plenty left to do. Notice I said paved. It skips a couple of good dirt ones specifically Kebler pass between Crested Butte to north of Paonia, Colorado. This is a great one especially in the Fall with the colors in full splendor.
