Query: Colorado Summit Fever

As with most 2nd editions the authors have enhanced their publication. Route descriptions are more concise and easier to follow. Plus, they have added a multitude of new photos which help you navigate your way to the Colorado summit. The addition of Broomfield County was a nice addition since it has just become a county.The 1st edition was a landmark production and the 2nd edition is just that much better. A must purchase for anyone who is serious about hiking/climbing to the highest point of each Colorado county.
