Former South Carolina Gov. Mark Sanford is perhaps the most famous person to not hike the Appalachian Trail. For six days in June 2009, the governor’s whereabouts were unknown — he wasn’t answering calls or text messages, and the national media was covering his sudden disappearance. Sanford’s staff eventually said that the governor was unreachable because he was hiking the AT, a statement that led to even more questions since one of the days he was “hiking” was Naked Hiking Day, an annual event when hikers hit the trail in their birthday suits. Sanford was later spotted at Atlanta’s Hartsfield-Jackson airport, and the story came out that instead of hiking the AT, the married governor was actually in Argentina engaging in an extramarital affair.
