I am getting ready to move into an appartment on campus. This will be my first year on my own, the previous years I was living with family. My mother told me I should keep nothing in my car and leave it unlocked, so that if someone does break into my car, there is nothing to steal and nothing is damaged trying to get in. My unlce told me however, that a homeless man had slept in one of his roomates car and basically ruined it (could not get the smell out ). So what do you think? I think they both have excellent points. My appartment has off street parking, but it is pretty close to a bar parking lot.
