The original proposal for this project called the general population’s spare time “an undeveloped power” and advertised it as “something to be dramatized.” Photos by George Masa and writings by Horace Kephart helped Myron Avery to plan one branch of this project. Mildred Ryder changed her name to Peace Pilgrim after traveling the length of this project. An expansive vision for building “community camps” as part of this project was proposed in a 1921 essay subtitled “A Project in Regional Planning” by (*) Benton MacKaye. In 2009, South (10[1])Carolina governor Mark Sanford (10[1])admitted to adultery (10[1])despite (10[2])earlier claiming to visit this project. An early controversy in the creation of this project centered around sharing a route with Skyline Drive in the Shenandoah Mountains. For 10 points, name this hiking trail that runs (10[1])from Springer Mountain in Georgia to Mount Katahdin in Maine. ■END■
