No stickers, no advertising /I have weapons/protected by S&W etc. IMO it's just advertising what you don't want people to know. The dog warning and a large water dish along with a lock on the fence gate is good advice. However, if you live in a state with snow - no paw prints in the snow tells it all. The big defference is who wants to get in your home - kids or career criminals. You have to be prepared for both. I've been thinking I might get a Honey Badger - that should cover the back yard at least.
Seriously, I agree with Steve in Vermont.
