My Side of the Mountain by Jean Craighead George

"The land is no place for a Gribley," Sam's Dad always says, talking about the farm that Sam's Great-Grandfather built, plowed - and then left when he realized he truly wanted to be a sailor.

Dad had been a sailor too, but Sam isn't sure that means that all Gribleys are meant for the sea. As a matter of fact, he's determined to go out to the Catskill Mountains and find the old beech with the family name carved into it. And when he does... Well, he might as well stay out there and try living in the woods. All on his own. With only a knife, some string, and flint'n'steel in his pockets.

Join Sam as he learns about the wild animals of the forest, works out how to catch fish and trap animals, and figures out how to make clothes from deerskins he's cured. Worry with him as he tries to start a fire and makes a home, keeping it hidden from hikers and forest rangers. Learn with him as he raises Frightful, a young peregrine falcon, to be his friend and fellow hunter.

I think everyone dreams of running away from home at least once in their lives. For those of us who don't make it more than halfway down the block, here's the adventure we might have had.
