Amen brother.
When I bought my property, the grandson of the old man I bought it from lived nearby and asked if he could continue to hunt here like he had his entire life. I gave permission but I continually had to pick up the trash he left behind. I like my woods to stay pristine and I get a lot of enjoyment spending time there. I had a talk with him about leaving his trash and he assured me it wouldn't happen again. After the following gun season I again found his food wrappers and drink bottles littered around the places he sat and I told him to get back there and clean it up or he wouldn't be welcome to hunt here again. I finally had to pick it up myself sometime later, he doesn't hunt here any more.
