It's a big day for Philadelphia, the Fourth of July.
The city's Celebration of Freedom Ceremony will be led by Mayor Nutter at 10 a.m. in front of Independence Hall. The hour-long event will include speeches, music, a fly-over by military jets, and readings from the Declaration of Independence. Thirteen people, symbolizing the 13 original colonies, are to become naturalized citizens.
Wednesday is also the final day of the annual Wawa Welcome America festival.
Following the ceremony, the Philadelphia Independence Day Parade will commence at 11 a.m.
More than 5,000 people - from marching bands to military groups and performers on floats - will wind their way around the historic district. It will be a tribute to the 11th Independence Day since the 9/11 attacks.
