The porcupine sculpture that was swiped from the driveway of the Portland International Jetport has been replaced with a new, cuter version, featuring a full-grown mama porcupine with a baby in tow. Porcupine 2.0 comes with a security upgrade, too: a large chunk of granite, onto which both spiny likenesses are sturdily affixed, meaning anyone who might have plans to abscond with the new sculptures better bring a front-end loader. The artwork, by New York artist Wendy Klemperer, was donated by June LaCombe of Pownal.
