Well thanks for all the imput guys and gals, Im back at the tank today so I can let you all know what happened. I decided to approach the the hunter. First let me clarify the setting, its a fairly open area around the tank with few spots to set up . The wind was about 5 to 10 from the south and we are on the north west side. Well after I sat and watched the man for a few min I decided to talk with him. I walked over and very respectfully asked him if he had seen my blind, he replied yes and that he was just going to sit right here. I then asked if he knew the first come first serve rule, jw said yea and that he Hayes confrontations on water. I said I agree but would have to ask him not set up right here because he is up wind and in the wide open about 20a yards from the water. He said no and continued to set up. I said okay but told him he was late to get here and cannot expect to not run into people if he shows up at water holes at 530. He was visibly upset ( hands and jaw shaking ) I began to walk away when he said your right and said he would walk out. I said thank you and told him I would be more than happy to let him have the tank the next day. He agreed and the rest of the hunt was fine and ended up watching a few small bulls come in but not the one we are looking for.
I'm back in the stand 2nite after watching several good bulls this morning in the same area. Hope they are thirsty!
Thanks again for all the impute.
