I wouldn't leave the house open in Calgary any more either. I left my truck unlocked for a night and someone stole my sunglasses, cell phone, and as we later discovered, our spare set of keys for the second car that were left in the truck. $700 later we now have new locks and keys for the Toyota. I am sure not going to leave my house door open for them to walk in. Although I have inadvertently left the garage door and the truck open many times before, no longer.
