you don't need a security system.
We bought an old home, a fixer upper, in the 80's. The wifey made me put locks on the doors when we could finally afford new windows a couple years ago. We don't need no stinking locks. We got dogs. In the 90's, our next door neighbor got ADT. He was bragging how they guarantee to be there in 15 min. "That's about the same amount of time for a theif to run from my house into yours and take all your schitt."
