If you go to Point Mugu Tattoo you can find a hidden Mickey on the sign that says "Paradise Pier".  Look between the words "Paradise" and "Pier".  You will see a design with a circle in the middle.  Inside the circle you will see three more circles that make up a classic hidden mickey.

Below is a picture of the Point Mugo Tattoo sign with the hidden Mickey.
