The 13th annual No Pants Subway Ride is set to kick off (all the pants) at 3 p.m. this afternoon. Which means today is a very good day for anti-pants activists, as well as people who are into acquiring communicable diseases from germ-ridden cesspools. [UPDATE:Here is our photo gallery of yesterday's spectacle.]

You can get all the relevant information about the event here. As always, people are encouraged to leave their cameras at home—but since some of you are obviously not going to do that, you should feel free to send pics to tips@gothamist.com, or tag them as "Gothamist" on Flickr.
