My town, Parker, CO, was just voted by CNN as one of the top 15 towns to live in. Little crime, 100's of miles of excellent bike paths, superb athletic and cultural facilities, lots of community involvement if so desired, etc.
Winters here are not nearly as "bad" as most people think. And, more sunny days than San Diego.
However, housing is more expensive than it used to be. The housing downturn barely affected us.
