That's funny, our cottage is right next to a State Park campground and the shoreline is usually pounded by people fishing. Not many people catch fish there because of the amount of fishing pressure. If I see guys out there I will usually walk to the end of the dock and see how they are doing and offer some advice. Funny how people think they own the water in front of their cottage. Realistically they put docks in the water where they don't own. In NY you own from the high water mark inland.
