Yosemite. Since you've never been to California before, if there's any chance that you might not go again, go to Yosemite. It's like nowhere else in the world. Even if the weather is shit, just being there to look around is incredible.
Though known for the big wall stuff, there's a fair bit of single pitch sport and loads of bouldering.
The big win is that there will always be someone around to hook up with.
