Allie Barkley, 14, of Monticello was all smiles Wednesday as she took part in activities associated with Camp Jabber Jaw, a residential camp for youngsters with communication disabilities. Her horseback ride at the Mississippi Horse Park was supervised by staff members of the nonprofit Rides-4-Him, a Caledonia-based therapeutic riding organization. Camp Jabber Jaw is coordinated by MSUs T.K. Martin Center for Technology and Disability.
