I will just give a few examples...
I have found empty beer cans, liquor bottles, and drug paraphernalia.
I have found trash like someone just cleaned out their truck in the woods, including fast food trash, empty cigarette packs and butts like they dumped them out of the ash tray, and even pornographic magazines.
I have found people living on the property.
I have found more ruts and tore up spots than I can count.
I have found one of my pecan trees shot up so bad it looked like that scene in Predator where they mini gunned the jungle.
I had a heifer calf with a bullet hole through her dewlap. She healed up fine, but three inches higher and she would have been buzzard fodder.
I have found poison put out for coyotes like I don't have dogs on this property.
I had a guy leave a gate open and a donkey got out in the highway and got hit by someone's car. Guess who had to pay the bill on that one?
Like I said, never EVER EVER EVER again.
The same goes for people that want to fish in your pond. I have a catfish pond that I stock every year. I have let a few people fish there over the years and its never good. They always come and slaughter the fish and take a whole cooler full home with them like I don't have to pay to put them in the pond and pay to feed them.
No one will ever respect your property the way that you respect your property. That is the truth.
I spent a lot of years living in the north. I understand that things are different there, but I grew up raising cattle, hunting, and fishing. I popped my first pinch of skoal when I was nine. I listened to both kinds of music...country AND western LOL. However, it wasn't until I moved to the south that I learned that people give ZERO effs about their hunting dogs. I ran rabbits with beagles for years. We ALWAYS picked up our dogs. Good dog...picked him up. Bad dog...picked him up. People in Georgia seem like they just turn their old dogs out at the end of hunting season and just say screw it, I'm not feeding them all summer. If you don't want the dog give him to someone or put a bullet in him. I can't even begin to put a number on the wild dogs that I have shot for running my animals.
The only way I would ever do it is if a professional guide stayed with the hunters the entire time and he would sign an agreement to be financially responsible for anything that happened.
Sorry for the rant.
