Emerson Elementary School sixth-grader Isaic Ford skids to a stop, the back wheel of his bike sliding out from under him. He dramatically falls to the Emerson gym floor, looks up and smiles a big, toothy grin. His bike helmet lies at a slant on his head and his glasses rest on the end of his nose. Emerson Bike Club volunteer Wendy Frankenburger extends a hand to help him up. She laughs and pats him on the back.
