Boston has recently experienced significant snowfall, with over 17 inches accumulating on city streets, leading to the return of the 'space saver' tradition. Residents use various objects like garbage cans, lawn chairs, and cones to reserve parking spaces they have cleared of snow. This practice is legal for 48 hours following a snow emergency, as per the city's regulations. However, tensions have arisen, with some residents resorting to vigilante actions to remove these space savers. The phenomenon is unique to Boston, although similar practices exist in other cities like Pittsburgh and Chicago, where they are culturally accepted despite being technically illegal.
