The summer of 2015 I worked as a Ridge Runner for the Connecticut portion of the Appalachian Trail. Appalachiantrail.org defines Ridge Running as
…seasonal employees assigned to hike and camp along high-use sections of the Appalachian Trail (A.T.) or to remain at heavily used overnight sites. The ridgerunner and caretaker program helps promote a quality recreational trail experience by talking to visitors about the A.T. and its intended primitive experience, its location, regulations, and traditions, as well as ways they can minimize their impact on the Trail.
Or, as Gage (my supervisor) says, glorified trash picker upper.
