Philadelphia
Philadelphia is the East Coast’s most reliably shaded major city for its size. William Penn’s 1683 grid runs the narrow streets east–west, and the Federal-era brick walk-ups are short enough to throw clean shadows without trenching the sidewalks into canyons. The model knows which side of Chestnut to be on at 2 p.m.
