DigProtek - Chairs you can count on.
"A parking chair is a chair that is used by a vehicle owner to informally mark a parking space as reserved. [...] In Boston, these are known as parking space savers or just space savers. [...] While use is year-round, it is a particularly time-honored tradition in heavy snowfall accumulation, when a resident who "digs out" their spot on the street essentially declares ownership, which often goes unchallenged by neighbors for fear of retribution." – Wikipedia
