A lot of people look to the outdoors to find peace of mind and relaxation. For Paul Stiffler, better known as Ponytail Paul, the Appalachian Trail and its thru-hikers have been the therapeutic force needed to turn his life around. Paul has taken on a role as “Trail Angel” to help thru-hikers on their 2,186-mile journey and help himself find a new sense of purpose in the process. You can take a look at his story in this inspirational video by REI.
