The diRosa Preserve is a 217-acre art park in Napa County, CA. We took the winter tour a few weeks ago, and loved it. I want to go back.
The main art gallery houses a permanent collection of some fantastic stuff — huge pop-art paintings, photos, weird kinetic and video sculptures (including one that shouted insults at me as I approached), even an art car from David Best (of Burning Man fame).
The tour guides were helpful, engaging, accomodating, and clearly knowledgeable. But they wouldn’t allow anyone to take photos inside the galleries, so my only pictures are from outside:Photos from the diRosa Preserve
There are a lot more photos (and better ones) at Flickr: dirosapreserve
