No we don't mind - you DEFINITELY deserve to vent after that one!
That is the kind of trespassing where you are driving home and figuring out how to wire 220V to the TH feeder.
Fortunately, you then remember that the authorities frown on that type of activity.
However, I would call your local sheriff, game warden, or other proper authority and file a report. Then if you ever do catch the guy, it will be much more difficult for him to argue that he "got lost" cutting through a field and has no idea how he ended up on your property.
