Grey skies and light drizzle couldn't keep the crowds away. Thousands lined Market Street downtown Sunday for the 2010 St. Patrick's Day Parade in St. Louis. It's the 41st year for the event, usually celebrated on the Saturday before the holiday, March 17th. One of the top St. Pat's parades in the country, the event featured over 120 units, including marching bands, floats, huge cartoon-character balloons, 5000+ marchers, and lots of clowns.
