I'm glad they weren't able to get into the house. There was a group in the Minneapolis area that was using the same MO to break into homes.
I like where I live because there aren't too many people around. But this type of crime is one of the reasons why I will not allow my garage to become a storage shed and my cars go in the garage and not out in the driveway.
Glad it wasn't worse and I hope your insurance will cover your losses.
