If you want to get in the front during football games you'll be able to, don't worry about that. You just have to act like you're the boss and get down in front.
Also, if you ever get up on 3rd Deck of Sampson there is a big map of all of the buildings that were around when Roosevelt went on his building spree. It started w/ the Rotunda and 3rd and 4th wing, Dahlgren and MacD, and then the whole Mahan/Sampson/Maury complex. The chapel was a couple of years later. There was also Isherwood or something at the time where Rickover now is.
Then again you may be able to wander in the food area.
