Passengers go pantless for 'No Pants Subway Ride' nationwide

CHICAGO (WLS) -- It's cold outside, but don't be surprised if you see people not wearing any pants Sunday while riding on the CTA.

The annual "No Pants Subway Ride" is taking place in Chicago and across the country. Riders drop trou all in the name of good fun. Those who take part are supposed to wear all their other clothing and act like nothing is wrong.

Pantless riders boarded trains at the Loyola Red Line station around noon.
