I wish I could get out to Colorado again. My buddy lived there for a few years. We visited him I think four times for a total of maybe 3 weeks. Not nearly enough time to enjoy that beautiful area. Colorado Springs was great and Boulder was fun. I didn't care for Denver though. Was very humbling seeing some of the wonders there. Garden of the Gods was great, Pikes Peak, etc. Not to mention the pool halls, college hangout in Boulder, parks, and on and on. This was probably 10 years ago now and we had a best of tour throughout the time we spent there.
