We return to postings about last weekend's trip to San Francisco with these shots from the de Young, the city's fine arts museum which was rebuilt after the earlier structure was seriously damaged by the Loma Prieta earthquake in 1989.
The most prominent element of the museum, which re-opened in 2005, is a 144-foot tower capped by a glass-enclosed panoramic viewing area. The building was designed by Swiss architecture firm Herzog & de Meuron, creators of the Bird's Nest - Beijing's National Stadium.
The copper skin of the museum eventually will oxidize to a green to match the surrounding part and lush landscape.
Even this diaper is too small for this pin.
Every turn inside and outside the museum brought another surprising view, like this one that greeted Greg and Tim in the central courtyard.
The tower offers a birds-eye view of the eco-friendly roof of the California Academy of Sciences.
