In New York City, candlelight vigils are held across the city on Wednesday night and Friday night at 7:00 PM. Impromptu memorials are put up at Washington Square, with hundreds of candles and flowers, and Union Square, where people write messages on large rolls of paper taped to the ground amidst candles, including a 6-foot high concrete candle. A mural is spray-painted on a wall in the Lower East Side. In the coming days the memorials continue to grow, especially at Union Square Park, where thousands come to congregate, grieve, and celebrate--the statue George Washington in Union Square overtaken as a shrine for peace, memory and the United States, thousands of candles are added, a metal sculpture of the American flag and 2500 roses planted in the shape of the World Trade Center towers.
Several thousand citizens march in a candlelight procession through the Adams Morgan district, through Dupont Circle, past dozens of embassies and onto the National Mall, where they join additional thousands of their fellow citizens holding vigil over the Pentagon, just across the Potomac River.
The Stars and Stripes appear on front stoops, flagpoles, cars, clothing, and on public buildings across the country.

Rev. Billy Graham led a service at Washington National Cathedral, with George W. Bush, the former presidents other than Reagan, Congressional leaders, other top officials in attendance. George W.
