I sometimes fantasize about going to prison, where I'd have my own cell and no one to take care of. That is, until I went to an actual prison and it seems not super hygienic in there!
I was surprised by the public access on the Alcatraz tour. We even tried out the solitary confinement cell.
Our ferry also took us to Angel Island, the Ellis Island for Chinese Americans. There are no rabbits or squirrels on the island, but there are a lot of harbor seals.
