just below Austin (The State Capital) TX there is a cavern with the normal stuff. But in one section they have what is called the aggie stone. Before you get to it they tell you that if you are over 5"6" tall you are going to have to duck. Everytime someone has hit their head on it they had gone to T A&M (So they say). But yes aggies are known as the not so bright college students that do tons of STUPID stuff.
