prickly pear cactus and winery
at Jack London State Park, which is also both a California State Historic Landmark and a U.S. National Historic Landmark, on Sonoma Mountain just up from Glen Ellen, Sonoma County

this building looks rather old-world, but that's probably because, we were told, Jack London hired Italian immigrants to build the winery and care for the vineyards

I don't think they made wine from prickly pear, however....
