We had a valid suggestion from Steve to look at Big Sur. He thought that the The Sierra Foothills would be too hot in June. I have been up there in June many times, and yes, it's warm. Keep in mind that Sonora is at a higher elevation. I have never seen temps over 90 though, usually in the 85 range. Big Sur is a beautiful area to visit, my only concern would be fog in the summer and I am not sure how many back roads are available for fun drives. It is also very congested in the summer but so is everywhere else.... We shall keep the doors open for now but we need to nail down a plan soon.
