I missed this post Brian, but now that I've found it.............
I already heard the story, as you know, the night before heading up to Wayne's place.
The situation was awkward as you were alone & these guys
didn't seem to care about private property or permission of any kind.
I have a great deal of patience and understanding, however, it runs thin at the signs of ignorance and stupidity.
In the same situation, it's hard to say what I would have done.
Thinking about it now, I probably would have let them go without too much fuss.
Post signs yourself at a height that's not easy for those asses to rip down.
Or a more effective method would be for me to stand guard while you go get your birds.
My skills @ human pest control far exceed my skills as a turkey hunter.
Whenever hunting the property in the future, you should take a quick check for their vehicle.
If you see spot them and know they're trespassing, call the police or MNR CO's and report the make, model & license plate.
The local police would probably be quicker.
