I live in Texas, in a military-esque neighborhood. So long as it doesn't pose a danger to the neighbors (i.e. ricochet into their yards), nobody will give a hoot.
Also, my dogs keep alerting me to the squirrels when they are in trees in the backyard. If there is lack of ricochet, I can shoot the danged things when my good girls are alerting on them, too, but without the risk to my dogs. If this thing can hurt my girls from anything other than a missed shot, then I will not be using it in the backyard.
I do have good aim but I need an 'air' gun to be legal in the residential areas, and I have no experience in these. That's why I tried the traps. Useless, useless things.
