Okay, someone will have to explain this to me:
Crews are continuing to search for a legally blind hiking magazine editor who disappeared along the Appalachian Trail in Virginia.
Some people searched throughout the night for 41-year-old Kenneth Knight of Ann Arbor, Mich. He was last seen at the shelter on Punchbowl Mountain near Buena Vista on Sunday morning and failed to meet up with friends on Tuesday. When he missed his flight home on Wednesday, friends reported him missing.
[...]
Knight was hiking a more than 60-mile section of the trail with friends.
There are plenty of physical activities I’d imagine blind folks might enjoy. But hiking is really a lot about sightseeing, and stumbling along a trail wouldn’t seem like much fun after the first hour. And what kind of friends would lose track of him? Keeping at least one hiker in front of him and one behind would seem a pretty basic approach. Giving him an emergency GPS locator/transmitter would seem a basic safeguard as well. Sheesh.
