When land owners do this, just wave back and smile. If they continue, pick up your cell phone, call the MP for them, since they would probably go into their home to complain about you for some made up reason (probably saying you were doing something illegal). Be the first to call!
Or perhaps take a video of the landowner, it seems that YouTube if full of actions like this these days.
Or maybe the forum water users (boaters) should start a rolling gathering, sort of a on-water-forum-fest. Pick a good place to anchor each weekend, and then many of us can try out all of these various places on the lake.
This way a lot of us would get to try different spots on the lake that we may never have thought of visiting, and we can get to know each other on the water.
I'm not talking about rafting in a no-rafting zone, but legally anchoring and enjoying the day.
