Another day, another opportunity to take off your pants in Portland.

The 2016 No Pants MAX Ride returns to Portland Sunday with a trip and a strip downtown on the train. Participants will shed their leg coverings but keep their skivvies, along the way gathering pants, hats, scarves and gloves for downtown homeless shelters.

As if public transit germaphobes needed any more reason to not sit down on the MAX.

The bare-legged riders - you might call them the fellowship of the traveling underpants - will meet at Skidmore Fountain under the Burnside Bridge at 2 p.m. They'll board the MAX to Pioneer Courthouse Square around 2:30 p.m., taking a group photo and dancing the can-can in front of Jake's Grill upon arrival.

After a return trip to Skidmore Fountain, those who are 21 and over can hit the after party at Shake Bar, where clothing donations will be accepted.

The event is Portland's take on a New York event created by public performance group Improv Everywhere in 2002.

Aside from the afterparty, organizers say it's an all-ages event (a 1-year-old was the star participant in 2014), so leave the stringy and see-through numbers at home. Stick with the tighty-whities or boxer shorts, perhaps.

And don't forget your MAX fare. A flash of your unmentionables does not $2.50 make.

The event's Facebook page suggests bringing a bag to store your pants in. Here's another idea: Arrive wearing the pants you plan to donate. What better way to show your support of those less fortunate than to give them the britches off your...backside?
