Oregon Walks president (and occasional WW contributor) Aaron Brown has launched a Tumblr feed satirically entitled "America's Best Bicycling City!"

So far, the page is a stream of photographs showing bicycle lanes blocked by gravel, parked trucks, and police stops.

Brown says he modeled the page on the car-shaming Washington, D.C. blog "Who's Blocking the L St. Bike Lane Today?" His goal is to point out how far Portland has to go to live up to its bike-utopia image.

"I'm still trying to figure out exactly how this blog could be something more than just having a laugh," he says.

He's taking submissions here.
