WASHINGTON (AP) -- Nineteen checkpoints have opened up at the National Mall in Washington, D-C, allowing people to stake out their spots for tonight's annual fireworks display.
Organizers are expecting a record crowd, and are trying to reassure the visitors following the recent attempted car bombings in Britain.
Security has been heightened. The mall is fenced off, and everyone has to go through security. Hundreds of emergency responders from about 20 law enforcement agencies are on duty, and a police helicopter will monitor crowds from above.
Crowds in Washington have reached 500-thousand people or more in the past.
