When Papa decides to pull up roots and move from Iowa to Oregon, he can't bear to leave his precious apple trees behind. Or his peaches, plums, grapes, cherries, and pears. Oh, and he takes his family along too. But the trail is cruel -- first there's a river to cross that's wider than Texas...and then there are hailstones as big as plums...and there's even a drought, sure to crisp the cherries.
