This shouldn't be a surprise to any UT senior. Jester and PCL both have an underground area open to everyone, and nearly every building has the 2nd floor as the ground floor. What might surprise most non-physics majors is that the tunnels shown here are only the first level. There exists a 3 story tall high intensity laser labortory under RLM. Doesn't everyone know they used tunnels to get to the tower and kill the sniper?
