A mass of humanity in St. Louis..
Obama just finish speaking in St. Louis under the Gateway Arch. Here is a picture on part of the crowd.
October 18, 2008
100,000 people

Lt. Samuel Dotson of the St. Louis Police Department placed the crowd count at 100,000 people, according to the campaign.
"All I can say is, 'Wow,'" Obama said just after taking the stage underneath the Gateway Arch.
Politico called Dotson to confirm the crowd figure but has not yet heard back.
If the number is verified, it would be Obama's largest American crowd, second only to the 200,000 people who turned out for his speech in Berlin, Germany, and more than the 80,000 people who attended his Democratic National Convention speech.
