You can have alot of fun with those gun free zone signs.

One thing you can do is if you live innercity is to put one on the door of your mortal enemy, then stand back and wait about 15 seconds and watch him get pack-raped by minorities...

But for the true patroit you have to use it against the criminals. Lets say you think handguns are the best for home defense but your neighbor prefers a pump action shotgun well why not make it into a competition? arrange a set time and tune in your wrist watches to match then simultaneously place gun free zone signs on your doors you will almost instantly have a steady flow of robbers and rapists flying through all sides of your house. so get killin'! after an hour of intense home battle take of the signs which will immediatly cut of the flow. Then get together with your neighbor and count the bodies scoring should go like this:

-10 points for every kill.
-1 point deduction for every ahot over one required to bring them down.
-For every headshot multiply that bodies score by 3x

Don't forget to organise ahead of time any special parameters of other bonuses for your own individual spin of the game!

And for a fun family day out without leaving the home don't forget to get your kids in on the game they'll love it!!
