The solution is really simple. Dig a ten foot deep trench around the wrestling mat. Fill it with 6 inches of glass. If you are pushed into the trench, you have 2 minutes to return to the mat or forfeit. I guarantee kids will try to stay in the center of the mat.
sorry chad i missed that suggestion coming through the grievance committee in-box. i forwarded the memo to facility maintenance, and they have begun digging. had to import the glass, seems most everything is plastic now. if the HA board of directors would approve we could fill with rusty nails instead. let me know, and i'll get on it.
