From Viva San Carlos online forum
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 to the gun shop for more ammunition. 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 from all the blood.'5. INSTALLATION COMPLETE! (It might help to get the note translated into Spanish. And hope the local burglars are literate.)
PS - I locked all four of 'em in the house. Better wait outside.'
