"The town still uses Olmsted's original layout, which some believe is reason enough to visit Vandergrift. '[Olmsted] designed Vandergrift, 35 miles northeast of Pittsburgh, with no right angles, instead following the curves of the river. He also used curving paths to blur movement among pedestrians and hedges to buffer commercialism. Street corners and the buildings on them were rounded. Parks dotted the hilly landscape, and the town was walkable.'"
