On our Bay Area visit we also stopped by the Bay Area Discovery Museum in Sausalito. That's across the Golden Gate Bridge from San Francisco, and across the Richmond Bridge from the East Bay (I don't think I had ever been over the Richmond Bridge before -- it's as impressive as its more famous co-bridges).
It's essentially a children's museum built on the grounds of part of the Presidio -- and not far from San Quentin where all California executions take place! Exciting!
We didn't stray far from the first building we went into, with exhibits on frogs (there's Austin on a lily pad waterbed with Cate) and other local wildlife.
Austin's also really into skunks now. It began with the "stinky skunk" T-shirt Baldwin sent and was reinforced by a cute board book at my sister's house called I Love You Stinky Face.
The museum was a pleasant way to spend an hour and a half, but it's one of those kiddie things where you really need to buy a membership because the regular admission prices are pretty steep.
Oh, and I should mention that I spent some time talking to Maia's daycare provider Tibor and he was incredibly nice. Great manner, calm and reassuring and friendly with all the kids. It'd be neat if Maia learned some Hungarian to go with her English and Chinese.
