Sand bags on the 100 meter range, ricochet prevention required by the inspector.
Because some people, in 2010 had goofed around and a stray bullet had somehow gotten outside of the walls of the range.
Highly debated, as the ballistic path would have had to been on par with the Kennedy bullet.
but the inspector says "not taking any chances, you guys gotta put up ballistic protection on those 100 meter walls".
Ballistic shields/plates are well out of our budget, sand, isn't, because it's at the coast, we get it from the city, for free.
