Our last day started off with a tour of the Stanford mansion! Apparently Leland Stanford (Sr) was the governor of California for a time and lived in Sacramento. The house, originally pretty modest at around 2000 square feet, was expanded to 4k and then 19k square feet.
After a really bad flood in 1862, the house was raised up and a relatively low-value ground floor added. That particular flood was so bad that Sacramento was about 10 feet underwater for 3 months. Afterwards, the entire city was raised a story, buildings and roads included. There are tours of the subterranean areas available during the summer.
We took Amtrak home in the evening, and then Caltrain back to our place!
