CENTERVILLE — Horse enthusiasts of all ages took part in the Pony Express ride through Centerville Friday afternoon. Leading the ride around the Centerville Square with the American flag is Roger Hildebrand, southeast Iowa Pony Express ride chairman. Hildebrand said he had 18 riders in Bloomfield and 22 in Centerville. "I didn't think there would be this many," he said. "Three years ago it was just me. And each year it just got a little bigger and a little bigger." Pony Express Riders of Iowa raise money for Camp Sunnyside. Pony Express Riders of Iowa is a non-profit organization.
