An almost unimaginable pairing — a painted gas pump and an oversized model of a soft-serve ice-cream cone, stand outside a restaurant in downtown Chambersburg, Pennsylvania. The pump’s art is devoted to the Lincoln Highway (now U.S. 30), one of the earliest transcontinental highways for automobiles across the United States. Conceived in 1912 it ran coast-to-coast from Times Square in New York City west to Lincoln Park in San Francisco, originally through 13 states, including Pennsylvania. Photo by Carol Highsmith.
