San Francisco

Great, there go my insurance rates again.

San Francisco, California, seems to be a multiversal sufferer of Transformers-related abuse. It has been targeted for nukes at least twice. Once successfully, and another time it was "only" contaminated by nuclear fall-out.

And yet the rent is so high. I don't understand. Makes you long for the days when it was only being savaged by weird robot bird-dragons that hatched out of asteroids or angry gestalts.
