In April, I suggested that Portland look into starting a bike-share program like the one recently launched in Washington, DC. And like magic, it's happening! (To be fair, I think the idea was on the radar long before I stuck my nose into the matter.)
Starting on Monday, June 9, Portlanders will be able to unlock white bikes around the city (using the White Bike code, which you can find at the group's website), ride them -- for free -- and then relock them for the next user.
