(Warning: AT Newbie Question)
As I scour maps to prepare for my upcoming (first) section hike of 112 miles, and seeing all the shelters plotted along the trail, I began to wonder if camping trailside at most any point along the trail was common? Or is it generally understood that reaching a certain shelter is the goal for sleeping for the night (whether in a tent or in the shelter)?
Suppose that I reach a point of exhaustion or hunger, and decide to just "stop there" for the night. Aside from private property, is it common to see tents along the trail outside of the normal shelter areas?
