I know how you feel. I grew up in Yuma, AZ and after having moved away, I still miss AZ terribly (and it's been almost 17 years). You'll find some great riding places when it warms, but don't let the winter keep you off your bike. When that snow melts, go find some nice trails.
Oh, and how strange is this? My childhood best friend lives in Surprise. Small world.
Stay warm!
