In Trenton, Baltimore, Boston and other cities, “space savers” are used to reserve parking spaces residents have shoveled out after snow storms. Now they are being used in Princeton to keep parking spaces empty as people move. All day today, three chairs have been blocking a parking space on Spring Street. Two more space behind the chairs was used by a moving truck all day. The meters for the truck parking spaces were bagged with “parking by permit only,” meaning those spaces were paid for so they could be used to move. This is the third time this week we’ve observed chairs or other items being used to save parking spaces in town — no shoveling required.
