poison would be a last resort.  But I am dealing  with a fellow  who will leave gates open or hangs them high so his goats & sheep can CROSS a COUNTY ROAD into my field at will. I am in a HERD LAW area WHERE YOU FENCE YOUR LIVESTOCK IN.  I told the fellow many time to KEEP HIS LIVESTOCK at HOME. He got assinine with me years ago 1 time, so to protect myself, I just call the law & let them handle it.  I do not have time to wait to catch his animals every time they are out & the field is 3-4 miles away.  The other neighbors are tired of feeding his livestock also.. His pasture is OVERGRAZED  shorter than most lawns.

Law shows up, but can not see his animals in a corn field, so they do little.  He dumps trash on my side of road.
