Forget the dogs, spotlights, alarm system and guns. Get yourself a Defense Mat.
The Defense Mat won’t really do much to scare the big bad men away, but what it will do is let them know right off the bat that you don’t have jack to steal… so they might as well move on to the neighbors house. Okay, honestly it won’t do that either.
It’ll simply get a good laugh out of guests, and that works for us.
