The only weapon I have is the slingshot that I bought at the Vermont Country Store a few years ago. I hung it on the back of my door as a deterrent. That worked for a while, but they wisened up and returned. As a last resort, I tried to hit a couple with stones. They quickly realized that they were safe. So here it stays...You could have lots of venison... they come eat your plants at the back deck..
In hindsight, I guess I could have been charged with transporting a weapon across the border.
