Not saying shoot at the guy, just up in the air... but yeah, it was tongue in cheek.
My approach would be to call down and see if he wanted a beer or something, I usually shoot for the overly nice until the person is proven to be an a hole.

A few years ago a group of hunters decided to put up posted signs right through the middle of my land. I about blew a fuse, but I took a day off to cool down, took down the signs and piled them up with a note and property map of where the border really was. I then welcomed them to hunt our land as long as they respected the fact we are out and be careful of our pets.

The signs were gone the next day, and I got a nice apology from the neighbors explaining it was friends of theirs who made the mistake. Never has a problem since, but I have accidentally screwed up some hunting for them a few times by walking the dog.

I have to tread lightly though as I have not lived here my whole life, and have experienced the attitude of lifers that don't like change. Small town rules I have to be careful with. Asbergers doesn't help me much either with the making the friends bit.
