My son and I have set up a nice little stand 100 yards past the end of a trail that runs next to a creek. We have been in there for the last month. Last night a guy drives his ATV right up the middle of the creek, right next to our stand and within 20 yards of our barrel and sets up a bait station and stand 200 yards from us. I'm feeling a little bit crowded. Nothing in the regulation says he can't do this. What are my options if I have any?
