I had a simular experience in bear season a few years ago. It got day light and next thing I new there was several people within 100 yards of me. It`s a big woods so I moved to a rock about 600 yards away. I was standing on the rock when a person came and setup about 30 yards from me. This pissed me off, but I didn`t say anything. I sat on my rock and about 10:30 he left. I stayed on the rock and about 1:00 he came back and set up in front of me again. Well this really pissed me off and I setup 30 yards bellow him and coughed, sneezed, played my radio moved all around to make as much noise as I could. I evan farted very loud. He finally shook his head and left. I would never setup on anyone else and if someone is going to do this to me its fair game.
