I explored the tunnels under my university two times. I was scared of getting caught, as the rumor is you get expelled. I decided not to say where because it is still to recent... maybe in a year or two I'll loosen up (then I'll be graduated).
The first time I was in the newer tunnels by the art building. It was great until I found a ladder leading up to a trapdoor. Of course I had to see where it led. As I opened it I tripped an alarm. Luckily, it was audible. The typical high pitched *beep beep beep*. I booked it out of there gashing my hand against the cement wall. I think I'll always have the scar. When I surfaced I saw one campus police car speeding to where I had been minutes before. As I crossed the street a second car pulled up.... and politely WAITED for me to finish crossed. Little did he know...
I swore I'd never go again. But I did. This time the tunnels seemed older... I splashed through a lot of puddles, and the spaces were more confined. My adrenaline was soaring. I got was nervous that I'd get caught so I began to look for an exit. I couldn't find one (the door was held fast under one building). I had to go all the way back the way I came.
There were lots of creepy room with machinery. And the tunnels are like a maze! I never knew where I was.
