August 22, 2009 (CHICAGO) --More than 1,000 people took part in an urban adventure Saturday called City Chase. It began at Daley Plaza with a quick workout. The teams did not know what they were in for when they agreed to take part, but organizers described it as part obstacle course and part scavenger hunt.
Teams had to rely on each other, the Internet and even strangers to complete their tasks. Organizers say the goal was to get people out of their comfort zone.
