When I was in HS (or college for that matter), I was always competing so I never got to see this kind of stuff actually happening. A short time after college, I got a part-time gig writing sports for a year or two to help make ends meet and covered a lot of HS sports. Holy shit. The parental activity was really something to take in, and honestly there were a lot of officials/refs that had no business wearing the stripes either.
Crazy shit, no doubt about it...
