Everytime cardeer,family is most likely exempt from chores,Find out where he is,and cut him off again,don't let him know where you are,Chain your stand to the tree with a padlock,use a climbing stick,and remove/hide it.You will probably make the farmer mad by insulting his family,but you never know..Maybe you should say something...HOW BAD DO YOU REALLY WANT TO HUNT THERE?I would be upset too,but what else can you do,besides show out,and leave,some people are just IGNORANT,and the son-inlaw sounds like one of them,he probably doesn't have the heart to hunt hard?
