This just happened to a friend of mine and I wanted to spread the word. Please crosspost this.
A friend of mine was out to dinner for only a few hours. When she came out, her car had been broken into. Suprisingly, they didn't take the car radio, but they took the garage door opener, and then took her regisration out of the glove box.
They then GPS'd their way to her house using the registration address, opened the garage door, gained access into the house and completely cleaned her out of electronics, jewlery and valuables. Luckily her three dogs were not injured, the robbers locked them up in the bedroom.
This is becoming a bit of a trend here in NC, with Charlotte in particular having had several of these in the last few weeks, but I doubt this is an isolated thing, and so I wanted to spread the word and say PLEASE DO NOT LEAVE YOUR GARAGE DOOR OPENER IN THE OPEN!!!! Also, keep your registration in your wallet, or someplace other then the glove compartment!
