Carlos desperately searched his pockets and his backpack, but there could be no doubt that he'd lost the key to his father's car. He and Gabriel were stranded deep in the remote mountain wilderness, where they'd ventured three days previously for an epic backpacking excursion. Now, with no way to get home, a frustrated Carlos ambled toward the brook to ponder the dilemma, when he suddenly stumbled awkwardly.
