naw, I leave my doors unlocked since I started following this guideline:
1) Go to a second-hand store and buy a pair of men's used size 14-16 work boots.
2) Place them on your front porch, along with several empty beer cans, a copy of Guns & Ammo magazine and several NRA magazines.
3) Put a few giant dog dishes next to the boots and magazines.
4) Leave a note on your door that reads: "Hey Bubba, Big Jim, Duke and Slim. I went for more ammo and beer. Back in an hour. Don't mess with the pit bulls --they attacked the mailman this morning and messed him up real bad. I don't think Killer took part in it, but it was hard to tell with all the blood. P.S. - I locked all four of them in the house. Better wait outside.
