The deal breaker for me would be the rain. When I lived in SE Washington State I delivered blood there three times a week for the red cross. It was always raining. I suppose one could overcome that with the proper gear. That and the infrastructure is supposed to be wonderful.

I like Denver. The city of Denver has nice cycling routes and plenty of MUPs. However, the major drawbacks are pretty much every suburb of Denver. Many do have plenty of MUPs but I would rather have ride able streets with halfway intelligent drivers not intent on making you a pancake instead of paths everywhere.
