By way of Clarence Eckerson, who is always keeping an eye on Portland, BikePortland has coverage of International Walk and Bike to School Day.
Did we celebrate that holiday in New York City? I was on a plane all day so, if we did, I missed it. At any rate, Walk and Bike to School Day was clearly a big deal in Portland. The Mayor, the transportation commissioner and lots of other local bigs showed up to pay tribute.
BikePortland has a nice photo gallery.
And for a little bit of historical context on Portland, check out Eckerson's Street Film: The Defeat of the Mt. Hood Freeway.
