Hundreds of cyclists braved the rainy streets of Portland on Sunday afternoon, many with their butts and breasts bare in protest.

Meanwhile, a few hundred marched from a park to the U.S. Immigration and Customs Enforcement facility in Portland's South Waterfront for a daytime protest decrying President Donald Trump's attempts to send National Guard troops to monitor the building.

"Whose streets? Our streets!" protestors chanted as they walked toward the facility with a huge banner that read "Abolish I.C.E.," accompanied by a marching band dressed in banana costumes.

Organizers of the World Naked Bike Ride scheduled an "emergency" ride Sunday to highlight "the militarization of Portland and the ongoing harm being done to immigrant and Indigenous communities," according to a joint Instagram post.

Riders gathered outside the Oregon Convention Center under gray skies and in just 53 degree weather.

Some came exposed to the elements while others wore clear ponchos over their underwear. Others wore fairy wings and kilts or Halloween costumes including the jack-o'-lantern suit of "Saturday Night Live" character David S. Pumpkins.

"We're cold, but not as cold as ICE," said a sign on one rider's back.

Cyclists followed a route south to the Burnside Bridge where they staged a "die-in," lying down next to their bikes before continuing along their route.

Onlookers at the ICE facility cheered the cyclists as they reached the building around 4:15 p.m. Sunday. The riders paraded in front of federal officers on the roof in a fashion show of rain jackets, Halloween costumes and nothing at all.
