This struck a couple memories....
First, when I was a freshman and finally attended my first Griz game (a playoff game), some dude in the student section actually had a train horn with battery in the stadium. It was freaking loud. The refs actually had to come to the side lines and warn the guy....it was pretty damn cool.
Secondly...fast forward....I remember a few years back, when those thunder sticks were popular, WaGriz had a promotion with them. Not since then.....Why not? I agree....Cow bells are popular at Ole Miss and Miss U seems to have their own thing.....Why not make it louder...regardless of the "rules"?? I'm still waiting to see either of those that come to mind get shut down in this day and age of the new "rules".
