Here's how it goes down: a person shovels out their spot when they leave and they place a piece of furniture in said spot to save it (usually a lawn chair, orange construction cone or even small pieces of furniture). If you are stupid enough to move the object and park there, don't be surprised if your car is f**ked up the next morning. Ghetto.
Not having to deal with this is one of the very few benefits of living in the burbs. Just my 2 cents.
