Deer hunting assholes; need to vent: pics added on page 3

So I put up a new deerstand on our property where deer are known to frequent two weeks before the season. I have been building the stand since June but the hurricane messed it up and put me behind schedule. We got it up and put feeders two weeks before the season.

My dad owns 65 acres of land, mostly a strip 96 feet wide. We had permission from the adjacent landowners on both sides of our property to hunt their property. Four on one side and seven on the other.
Last summer the propert right next to us went for sale, 18 acres with a bayou side lot and small shotgun house for 150,000. My dad helped his buddy acquire the property. His buddy said he would let us hunt the property and would just hunt one of our stands if he wanted to hunt. He hardly ever hunts.

He buys the property. Enter his son. The son says he won't put up a stand near ours. One week AFTER the season starts a stand goes up 60 yards past mine cutting my throat. No problem, it's their property. He kills a 90 pound doe and a 45 pound button buck in the ensuing weeks.

The other day three does come out on the property past him from my stand. I have permission to shoot on this property, he doesn't. Respecting him being in his stand I don't shoot. I haven't killed a deer in a few years and would have taken a big doe. He was waiting for a buck so I didn't shoot.

We ge to our stands early and are in there at least 50-60 minutes before shooting time. He gets in his stand 15-20 minutes before shooting time riding a four wheeler about 100 yards from my stand and parking. We took him duck hunting a few times.

The last straw came tonight. I called my dad who went hunt my stand. It's over a crawfish pond which has been overrun by otters. He wanted to shoot the otter. Two deer came out at 5:00, which he let walk cause hey were does. At 520 pm here comes the jackass son on his four wheeler. Parked almost even with my stand where my dad is and walks to his stand. Not there ten minutes and POW shoots another 50 pound deer. Goes get the four wheeler picks it up and leaves! He doesn't know how to clean a deer, my dad cleaned his last two. His dad doesn't either.


I am going in my stand this weekend and will shoot every living fricking thing I see if he is in that stand. He also put up two more stands where we have stands with feeders on his property. The feeders are coming down tomorrow. We don't think his dad Knows any of his is goin on but aren't sure.
What else can I do? It's their property and they have the right to do what they want. I'm thinking about going put a stand on the property on the other side of him which is owned by one of my best friends since elementary school.

TL:DR. GFY

OH I'M MAD
