Directions
to the Cannon Room from the Quad (orange line on map below):
When you are facing the
Quad, walk up the RIGHT set of stairs and along the walkway until you come to glass
doors on your RIGHT.
Go through the two sets of
glass doors and make an immediate LEFT (a security guard/desk will be on your
right).
You want to go LEFT and walk
through a green set of doors. Keep following the hallway and the Cannon Room
will be on your LEFT in a short time. If you have come to a black and white
checkered walkway, you have gone too far.
