You can imagine her, can't you? A 65-year-old woman, visiting from Ohio, getting up on a spring morning, deciding to take a hike. She puts a few items in her fanny pack, makes sure she's got her camera, sets out to enjoy a day in the mountains. She's on vacation, out for a little exercise on no particular stretch of trail, just a section of the Mountains-to-Sea running along the Blue Ridge Parkway near Asheville.
