Go back to the days of the great explorers. Let your children wander around in the stories of granddad and grandma. Get unplugged. In these modern days they are gaming on their IPad, Nintendo or X-Box or do Pokemon Go, but don't know how to build tree houses and pick berries. Have they ever woken to the sound of a woodpecker or the rustle of a deer or horses galloping by. Do they know an oak from a beech?
