On this self-guided tour, you will be treated to an in-depth history — told in American Sign Language — of our philosophy, museum, building, secret doors and what to look for as you head out on your super sleuth adventure.

Find your way through secret doors and covert passages to a world never experienced. You'll be walking in the footsteps of presidents and freedom fighters, historians and fiction writers.
We will never ruin the surprise of finding a secret door by giving you a map - or showing you where they are. So be sure to keep your eyes open! If you find two secret doors you are an above average sleuth!
