Thanks for all the help guys. I have decided I'm doing Alpine for sure. I'm trying to lock in a Winery now too.. so any suggestions on a San Diego Winery that I could stop at after Alpine. I'm going to try to go to Alpine for a noon tour and then drive to San Diego for a wine tasting. Let me know if a noon tour is not possible since they are closed today and I couldn't find anything on their website. I don't know too much about wine so if there is a good one to go to please let me know. I'm trying to get this all planned so please help.
There really aren't wineries in San Diego. You'll have to go to Temecula, and that's a fair drive- they're all pretty much in one spot up there.
