This is going around the internet and found its way to my inbox and I think the tip is a great one.
If you have a GPS in your vehicle. Don't have the "HOME" key programmed to your exact house. Program it to something nearby such as a grocery store so you can still find your way home from there. According to the e-mail, someone was at a football game and had their car broken into. The thief now had their garage door opener to get into their house and had a GPS to locate their home. The thief knew they were at the football game and about how much time he had to break in.
Another thing. I know you are supposed to have your vehicle registration in your vehicle at all times and these also have our home addresses on them. This is a law that absolutely drives me nuts for the above reason. Don't keep your registration in your glove box. Put it in a zip-lock baggie and then tape it somewhere inconspicuous.
It is sad we have to be so cautious, but an ounce of prevention can be worth a pound of cure.
