Floating hand in hand, 620 people formed a U-shaped line on the Willamette River in downtown Portland Friday morning.
They unofficially set a new world record, topping the 542 people who floated in a line in Viareggio, Italy in 2008.
“The bar has been raised,” said organizer Will Levenson, who estimated the human chain would have stretched about a half-mile if the group had formed a single-file line. “Ultimately, it’s a really fun, artful statement. What a great way to express that we love our river.”
Today’s tally will have to be verified by Guinness World Records before it becomes official.
The water was a balmy 72 degrees, and helicopter drones flew overhead to document the occasion. Portland start-up GigaPan created a high-resolution panoramic picture of the floating line that allows participants to zoom in and tag themselves.
