Quote:As you’ve probably already heard, we built this city on rock and roll. But Peter Root carved his out of 176 lbs of potatoes. Officially titled "Plot," the miniature spud city was inspired by Root’s surroundings of Istanbul. It took about three weeks to complete and consists of very starchy homes, office blocks and places of worship. Take that, Starship.
