The stand thing to me is ridiculous and should not be allowed. Guys think because they hang a stand they own the place. The worst case is you get there  early go get in your stand and some guy comes in mad saying you have set up 100 yards from his stand. So you are supposed to see the stand in the dark and know the area belongs to them? That is exactly why I will not put in for a place that puts 2000 people on a hunt. Here is the deal if I pull up to a spot I have planned to hunt and truck is there I just move on or if they are still at their truck and I can ask where they are going and it's totally different directions than I go on to my spot. If your dad and son beat them there to the parking spot then the other two should have respected that and moved on in my opinion. LBL is the worst for the " I got my stand back there" scenario. I will never leave my stand on public land , if you beat me/ it's your spot. Courtesy has went out the window with most hunters now days. I hope your dad and son both kill big ones this morning!
