Members of the U.S. Navy parachute demonstration team, the Leap Frogs, wave to spectators after parachuting during the opening ceremony of a Chicago White Sox baseball game at U.S. Cellular Field during Chicago Navy Week. Chicago Navy Week is one of 20 Navy Weeks planned across America for 2010. Navy Weeks are designed to show Americans the investment they have made in their Navy and increase awareness in cities that do not have a significant Navy presence.
