Pittsburgh's Washington's Landing is largely a quiet place with the occasional rower skimming the Allegheny River or a runner looping over the landscaped trail. Once an industrial brownfield, it's now a small haven that boasts the brightest autumnal palette (and a connection to George Washington himself). In short, it's an ideal spot for a picnic, and fall picnics call for thermoses of piping hot Curry Pumpkin Soup!
