Sam Gribley is terribly unhappy living in his family's crowded New York City apartment. So, armed with just the bare necessities -- a penknife, a ball of cord, some flint and steel, and the clothes on his back -- he runs away to the mountains. There, Sam must rely on his own ingenuity and the resources of the great outdoors to survive -- and he discovers a side of himself he never knew existed. Book jacket.
