These are the stories that defy conventional logic. The proverbial vanished without a trace incidences, which happen a lot more (and a lot closer to your backyard) than almost anyone thinks. These are the missing whose situations are the hardest on loved ones left behind. The cases that are an embarrassment for park superintendents, rangers and law enforcement charged with Search & Rescue. The ones that baffle the volunteers who comb the mountains, woods and badlands. The stories that should give you pause every time you venture outdoors.
