My husband (in sketch) and I flew into the Bay Area for a quick weekend. We visited the DeYoung Museum in Golden Gate Park in San Francisco. What a fantastic building with plenty of interesting exhibits. It turned out to be a beautifully warm day. We had lunch at the museum cafe outside under the cantilevered overhang. It was so enjoyable, I just wanted to linger. It smelled of the eucalyptus trees.

It's a definite 'must see' when in San Francisco.
