Well, I've had a pheasant hunter fire a gun from behind me and just to the left of my left shoulder, aiming for a bird that was in the road just ahead of me.

And I've had people hunting groundhogs for sport, shooting right through my yard when I had a small child and a dog in the vicinity.

And another time some hunters actually did shoot my dog.

I don't know about concealed weapons, but I sure as hell think people who use guns for sport need more legally required training in how to use them responsibly. I think I'll go over and post this to the other thread.
