I just put up some signs from an alarm company (I don’t actually have an alarm) and a “Beware of Dog” sign (I have a cat) and I park my truck that has an NRA sticker in the back window in the driveway.
So far the only intruder I’ve encountered was a raccoon who came in the cat door.
I don’t think the raccoon could read. He left before I could shoot him.
Well, deers can read so why wouldn’t a raccoon?
