Dylan was fascinated by all the trolleys, trains, and double-decker buses in San Francisco. We didn't have much choice except to ride each one of them at some point. Here's Dylan taking in some city views during the double-decker bus tour through downtown San Francisco.

Another one of Dylan's favorite activities in San Francisco: playing with sand.

Dylan was quite enchanted with the waves coming out of the water caves.

It's scary spider Dylan!

For some reason we can't quite understand, Dylan was quite taken with the pigeons in San Francisco. He followed this one all around the entrance to the Bay Area Discovery Museum.

The view of the Golden Gate Bridge from the Bay Area Discovery Museum in Sausalito. We met Martha and Bea here and played most of the day. The facility is an incredible hands-on experience unlike any we have here in Seattle.

The view of Coit Tower on Telegraph Hill from the Embarcadero.

A blurry pic, but we like this one. Dinner at Calzzone's our first night in San Francisco. Calzzone's will always have a place in our hearts. Just ask Hannah about it!

Just a sample of the many dozens of types of intricate carvings and art that adorns the storefronts in Chinatown.

Dylan's favorite part about the trip to San Francisco? The blinds in the hotel room.
