This seems to be going on a lot.. From stuff I've heard on the news around here is that basically kids are bored and going around checking if people leave their cars unlocked. In most cases they haven't been taking anything. Sorry to hear that they took stuff from ya
I was over a friends house during the winter, I was leaving and noticed my friends car door opened. All the compartments were opened but nothing taken. Noticed foot steps in the snow leading to my car as well but I had my doors locked
Kinda just makes ya a little uneasy.
