Pope John Paul II will be beatified in May, which puts him halfway toward sainthood. To have gotten this far, the Vatican must believe that the late pope is responsible for a miracle. Earlier this year, the Vatican declared that a woman was miraculously healed from Parkinson's disease after she prayed to the late pontiff.
And this raises the question: How does the Vatican investigate miracles?
Let's start in Ferndale, Wash., where a potential miracle is under investigation.
Terry Button is a fifth-generation farmer from upstate New York who also works as a long-distance trucker, hauling hay and produce up and down the East Coast.
He's proud of his truck and likes it just the way it is. Inside, the cab is homey and low-tech, with a bed behind the two seats and a CB radio. There's no cruise control and no GPS telling him where to go.
