UPDATE*****
I did take some of your guys advice, and talked to the guy that was kinda screwing things up. I started off trying to be nice, but as expected he wasnt hearing it. He didn't seem to care that he wasnt supposed to be on our part of the farm, or about driving past my vehicle just to park out in the open. After a brief argument, i pulled away pissed off. I stopped in the middle of the lane, walked back to him and tried again. An hour and a half later peace had been made. We exchanged numbers, to let eachother know when we would be out. He invited me to hunt some killer property he has in another county. He just texted me this past weekend to let me know he intended to take his stand down. He's only after massive deer and he hasn't seen any. He's a real serious coyote hunter. He sells sounds, videos, etc.. Gets free gear thrown his way. Dude has night thermal scopes that record what he's seeing. He actually showed me video and gave me the location where the groups of the 5 year old plus bucks hang out til rut. The videos of those monsters were impressive to say the least.
So after all that, he still insists that the deer dont care about vehicles out in the open, but i will take it as a win
