2009 No Pants pictures
"The 8th Annual No Pants! Subway Ride went off without a hitch today in New York. It's tough to count, but we're guessing we had between 1,200 and 1,500 participants. Riders were divided up and dispatched to 4 separate train lines. The high was 30 degrees and there was a nice steady stream of snow." [Improv Everywhere]
