Its an industrial building tucked away in the middle of the same industrial park that Edelbock and Russel are located. No listing in the phone book, no sign outside on the building, nobody at the front door to take your money. You either know where it is, or your don't. Not open to the public. You either have business there, or you don't. He has an open house once a hear for charity. Other than that, its his personal garage/shop. No different that Leno's.
The Peterson is a museum. The Henry Ford is a museum.
