Volunteers from all over the world have come to Joplin to help residents and the city rebuild since the May 22 tornado. They’ve left behind more than the fruits of their labor. They’ve also left their own messages of thanks and encouragement like this one, written on the walls of a special seating area of reflection at Cunningham Park, the city’s main public park that was destroyed by the tornado and is now rebuilt.
