Hundreds of Restonians showed their love of their Nature House Saturday morning by participating in a charity race. Reston's founder, Bob Simon, 98 and going strong, showed his commitment to the fundraising event by overseeing the early morning warm-up for the racers. Participants ranged from age 6 to 76 and along the entire 5K (3.1 mile) course they were greeted by cheering, encouraging wellwishers.
