i too once faced the underhanded cowardice of fence jumpers luckily i know a thing or too about people and their tendancy to avoid anyone with a sword.... well its true i am a martial artist as my name may imply but you dont need to be one to have a sword and look scary so my advice... get a nice sword like a katana and maybe put a few of them big ol rat traps in the yrd all around just behind the fence paint em green and leave em set theyve been known to break fingers and toes and jump almost to nose hight that should teach thos filthy bastards ............. i love toast its so crunchy and warm and coverd in jelly ..... just like my ex girlfreind
