i had 2 young boys trash my pond , pulled plants and threw them at each other. went out in the boat playing around. just made a mess of everything. i don't blame the kids , i blame the parents. what if one hit his head diving off the dock , by time other went for help , kid be dead. i did some research and found if you try to prevent an accident things will go your way. the pond is acre , so i electric fenced from my barn to the perimeter of my property back. i made the attempt to keep people out. also kicked my insurance up to a mil liability lol
