'Tis the season for 'Chicago dibs' on snow-shoveled parking spaces

With winter officially here, it's time to revisit the unique practice that is "Chicago dibs."

After shoveling out their cars in the morning, Chicagoans like to protectively call "dibs" on the hard-earned spot for when they return later. These unofficially reserved parking spaces are held by everything from cones to chairs to full tables. And the Chicago Dibs Tumblr collects photos of dibs all over the city:
