35,000 Hear Obama Speak

Huffington Post - "Barack Obama was greeted by the largest crowd of his campaign Friday night in Philadelphia. Some 35,000 people jammed into Independence Park to see the Democratic presidential candidate, four days before this state's crucial April 22 primary.

Frank Friel, director of security at the Independence Visitor Center, made the official estimate.

The crowd exceed the 30,000 who greeted Obama and Oprah Winfrey in December in Columbia, S.C."
