I lived in CO as a kid for first 12 years. love the place and visit often. was planning on a trip out to CO this summer with my newly acquired GSA and this will be perfect. Bing maps are nice and all, but you will help out in a HUGE way. I just hope my GSA can get over that pass above Telluride. I saw that while looking over maps. Thank you. BTW, No fear of heights here.
