Where are we?

My girlfriend Chelsea set up a trip to California for the two of us for my 30th birthday back in 2011. We did some sight seeing, a lot of wine tasting, and ate way too much good food. I had a great time, and it felt like a proper goodbye to my 20's. Thanks to some family connections, Chelsea was able to get me a tour of a place I've wanted to visit ever since I was a little kid. As much as I'd love to go back there again, it's probably one of those once in a lifetime sort of deals. No matter, as the memories I have will be more than enough to bring a smile to my face years from now. Here's a shot her uncle took of us while we were there.

I'm sure it's pretty easy to figure out, but maybe not. I'll give the person that gets it right an enthusiastic thumbs up. Good luck !
