At the time of our hike, the Appalachian Trail was fifty-nine years old. That is, by American standards, incredibly venerable. The Oregon and Santa Fe trails didn’t last as long. Route 66 didn’t last as long. The old coast-to-coast Lincoln Highway, a road that brought transforming wealth and life to hundreds of little towns, so important and familiar that it became known as “America’s Main Street,” didn’t last as long. Nothing in America does.
