Good idea on the "roof"!I think I'll try to find one of these cutting boards, but larger, to put in my .22 PB rifle target range. It's only 50 yards, but I have 2 layers of plywood, plus a bale of hay, and some of them still go all the way through. Fortunately, it's in an area where nobody (and no property) can be hurt, but I still don't like the idea of projectiles flying about!
I can't believe this never occurred to me before. I'm always scrounging up various pieces of old lumber scraps and such, when this will hold up in the weather much better.
