Seems to keep the scrags away here.
My back yard is a thouroghfare for folks traveling from one Project to another. Can't put up a fence, so there's not much I can do to stop it (unless you know a supplier for Poison Ivy Seeds...)
OTOH I have a 12" "shoot-N-see" target pasted right by my back sliding door. It has 13 VERY visible .50 holes in a decent group in it. I've also been seen in the late of night on my screen porch holding a ribcage in one hand and a hatchet in the other while covered in blood....
The average Project Hoodie can't tell a Deer Ribcage from a Human ribcage and the guy who saw me in that condition was suitably freaked.
I've also pointed a Glock into the face of a looser who had the bad judgement to illuminate my wife with a laser pointer... but that's another story.
Funny though, of all the townhouses/condos in my circle, mine is one of the only ones never broken into. Can't figure out why...

C2N14... because life is not energetic enough.

Not Depressed enough yet? Go read National Geographic, July 1976
