Sacramento has one of the coolest museums for kids, and for adults for that matter. Its the Railroad Museum. It houses all sorts of trains that you can run around in, new and old. And best yet, the top floor is devoted to Thomas the Train. Max and Kaitlyn were in heaven!!!! I love our play dates with K. I love watching them play off each other and talk in their toddler talk that no one understands but them. And K's mom is pretty cool too.
