What's the best location for year round riding?

I'm kind of playing with the idea of changing things up. New career, new location.

I'm a computer engineer, with 5 years experience developing software. My wife is a teacher, with roughly 10 years experience at all grade levels up to middle school.

Let's say I want a decent job and a nice place where I can play outdoors (mostly riding) year round. Where would I go? My wife says she can get a teaching job just about anywhere, and will go wherever.

Also, bear in mind I'd like a good place to raise my son. He's going to be 3 in December.
