As much as I would like it to be, a thru-hike isn't an endless stream of joyous experiences. There isn't a new and gorgeous view around every turn. Some sections of the trail require a slog through boring or difficult terrain before reaching more enjoyable scenery. An uninspiring landscape must occasionally be endured for a day or two before finding another beautiful vista.
Still, I can usually find something of interest daily along the trail, even when the terrain doesn't offer an inspiring view from a mountaintop.
