Clint Eastwood ... has served one term mayor of this tiny coastal city of Carmel.
Majority of the people live in Camel are wealthy and famous. As a strange local law, this is the only city in North America without any residential address. For the privacy reason, everyone uses a mail box. So, the post office is where you can possible meet every single one of the faceless invisible resident here.
