For many Seattleites, the opening of Sound Transit's new Husky Stadium and Capitol Hill light rail stations will mean better and faster ways of getting around the city. For Kelsey Wildstone, organizer for the Emerald City Improv troupe, the new stops represent new opportunities to take off her pants in public.

Wildstone leads the annual No Pants Light Rail Ride, which is exactly what it sounds like: A group of people ride the train wearing only their skivvies below the waist. Inspired by the NYC prank collective Improv Everywhere, she first orchestrated with her former improv colleague Luke Greenaway in January 2010, just six months after the light rail got rolling in Seattle, and has kept it going every year since.

Although the group's next light rail ride isn't slotted until next January, with all the buzz around the new stations, there's no telling when their pants might drop next.

What advice can you offer the first-time No-Pants Light Rail Rider?
The cold factor is probably the biggest thing. That's what people see and that's what makes it funny. It's a cold day and you're not wearing pants. People are like "What the hell!" It's usually the second week of January, in the January doldrums.

How do you help people get comfortable with public undress?
Just in past years, people have made comments to me that they felt that it was a very body-positive event. People felt very comfortable with however they looked. ... I think those kind of things are what help somebody develop more confidence.

How do the pants-ed passengers respond?
Sometimes the negative reactions I've seen haven't even been in person. Thinking about it more, it's actually more that I see it online in comments, of course, because people can say things that they wouldn't say to your face.
