Jim Gallien had driven four miles out of Fairbanks when he spotted the hitchhiker standing in the snow beside the road, thumb raised high, shivering in the gray Alaska dawn. He didn’t appear to be very old: 18, maybe 19 at most. A rifle protruded from the young man’s backpack, but he looked friendly enough; a hitchhiker with a Remington semiautomatic isn’t the sort of thing that gives motorists pause in the forty-ninth state. Gallien steered his truck onto the shoulder and told the kid to climb in.
The hitchhiker swung his pack into the bed of the Ford and introduced himself as Alex. “Alex?” Gallien responded, fishing for a last name.
“Just Alex,” the young man replied, pointedly rejecting the bait. Five feet seven or eight with a wiry build, he claimed to be 24 years old and said he was from South Dakota. He explained that he wanted a ride as far as the edge of Denali National Park, where he intended to walk deep into the bush and “live off the land for a few months.”
