[Highland Park] Lock your doors!!

I opened my back door last week to let the cool air in and may have forgotten to close and lock it. In the morning, my keys were missing. I would have never thought that someone had taken them except that two pounds of strawberries--go figure--were missing from the frig. I would have just gotten another set thinking that I misplaced them. I think that there is a group going around at night to find back doors left open or unlocked because it is summertime. They take only keys--except for strawberries--and then come back when the residents have left. It's alot safer for them that way. Needless to say, I changed the locks on all the main doors. Words to the wise. Blessings, Steve
