PHILADELPHIA (CBS)—With snow in the forecast for Friday the Philadelphia Police Department is reminding residents that saving parking spots is illegal.

The “Game of Cones” as they call it, or also known as “savesies” is the act of saving a parking spot by placing a household item—sometimes a cone—to save their spot during inclement weather.

Police say the street doesn’t belong to you and that they should be called if  “spot saving” commences.

“Please don’t get into an argument with another person over a parking spot,” police said on their Facebook page. “If you see someone saving a spot, just give us a call and we’ll take care of it.”
