I lived there until I retired and moved here in 2013. When I retired I had lived in the Napa Valley for 14 years and not once did I set foot in a winery as I don't like wine. There were also micro breweries all over the place and I never entered one of those either, and as far as I know neither did any of my friends.
The closest I've ever got to drinking a 'craft' beer is Henry Weinhard's and Sierra Nevada. I used to drink them almost exclusively back in the 80's and 90's, then for some reason I got out of the habit. It isn't available here but it doesn't matter as these days I only drink lite beer. I really can't handle regular beer anymore as it has too much alcohol and I get a buzz after just a couple. And since there really aren't any "good" lite beers out there I just buy the cheap-o stuff like Natural Lite or Milwaukee's Best Lite. I can get a 30-pak for about $18. That's almost enough for an entire weekend.
