I live in Spokane Valley Washington, so we have 4 honest seasons. Slightly Hilly terrain, but amazing riding thanks in part to our Centennial trail. Essentially a freeway for us cyclists. Lush forests and a beautiful river. High heat is 100 f. Winters can be cold, but not too long. Snow is not major, though present. Having been born and raised in Alaska I find this place close to paradise. Also the highway Dept. is adding bike lanes on all new road construction, which is a bonus. We also have a "share the road" program and laws in place. I think that the Spokane area is quite bike friendly.
