You are a facility owner. 3 days a week you rent to H/J shows. All mounted people must wear helmets on those days. 3 days a week you rent out to Western sports. Helmets are not required.
Your facility is made out of metal and you like to park tractors in the ring during speed events. But its OK because everyone knows only jumping is dangerous.
I chose one without small children getting smashed into metal fences.
