When I was at WVU ('73-'79), our fraternity had a cannon that actually fired (Kappa Alpha, just down the street from the Sig Eps). We used to stuff things into the cannon and fire down onto the Mountanlair deck (the student union). Never did it sober, though.
That and the HUGE Cerwin Vega speakers we put out that you could hear across campus and made for great Friday afternoon experiences... providing music to many that occupied the Mountanlair deck (and the Science Department, among others)... sorta like a public service. Also, never sober.
Never destructive (unlike certain other frats). Just clean fun and drinking in the mid 70's. College would be no fun today, I suppose.
A bunch of tripping brothers came home to a bottle rocket assault by some drunk ones, back in my day. Damn drunks, they scared us to death. But you catch some mean trails off of a bottle rocket soaring up a staircase, right at your head....
I can't help it - I have to mention that my mother won $25 for her winning entry in a contest to name the Mountainlair.
