We haven't needed a fence, here....
But, I have had a problem that a fence would not solve.
Several of our past and current neighbors just LOVE to burn.... I swear, it has been like a favorite daily past-time for them.
Here I am, with a dog and a kid who is on Xyzal, shots, etc... and there were times where we couldn't even to outside or open the doors.
There were days that we just up and got in the car and left.....
I finally said something to one neighbor, and that helped....
A couple of these neighbors have gotten older and moved off.
But, the one lady next door takes the cake. We were having a roof put on our house. She sets up her burning just feet/yards away... right on the property line... finding anything she can, even 'green' debris, to burn. I think she had to put kerosene or something on it to light it and get it to burn.
Billowing clouds of toxic, nasty, black smoke going right over our roof.
I had my son say something to her... that helped, momentarily.
Next morning, the roofers showed up to finish the job... She starts the fire AGAIN.....
I didn't say a word. Just turned on the garden hose on that side of our house, pulled it over that way, and spayed away putting the fire out.
Then walked off.
