As noted, Delores Point and the annual Spring & Fall fly-ins at La Garita ranch are great spots (permission req'd). But there aren't any spots in Colorado that compare to Johnson Creek type (with it's free Wi-Fi, showers, nice grass runway, caretaker, etc). There aren't any spots on the East side of the Continental Divide that I know of that I'd camp at as a destination. Numerous (friendly) private strips, but again none that compare to Idaho. PM me and we can talk/exchange more detail if desired...
