well all things considering what i would do , Now you better consult a lawyer on this one .
Anyways look out in your back yard where ,,, if you were a thief you would enter , Also look from roadway as well.. then i would purchase some cheap 4 x 8 sheets of plywood or what ever then i would also purchase 6 " nails cut 4x8 sheets in half so 2 x 8 place them around fence line approx 2 feet away ( outwards or just jump your own fence to see where pain line will be hahaha
from the fence cover it up with what ever brush grass clippings soil so its not to noticeable
If and when rippers do hop the fence nothing like getting nailed on the spot imagine 6 " nails going into your foot and not one or two like bunch, also i would sharpen tips
now a Friend did this once as school kids were always jumping his fence and taking a short cut he got in serious shit but i think he beat it as to he used a excuse he was working in the area and must of forgot about the nailed boards
I also wanted to do this being i am a corner lot and fuckers in back alley always cutting turns sharp and fucking up the grass on curb side thought couple 2 x 8 with nails hidden and these fuckers would have Flat tires would teach them a lesson ..
