Thursday's edition of On Point with Tom Ashbrook (a radio program broadcast on WBUR Boston and featured on other NPR radio stations) featured "Cyclist Culture: Pedaling Attitude."

The episode as summarized by the program website: "America is car country, but bicycles and bicyclists are making their play for the roads. There’s been a big surge in bicycle commuting. Maybe it’s you or your workmate rolling freshly-exercised into the office. And then there’s the weekend distance rider and the off-to-the-market rider. All the tribes: the roadie, the mountain biker, the messenger. And all the attitudes: the righteous cyclist, the lone wolf, the captains of contraption. We’re talking this hour with New York’s famous "Bike Snob" blogger and a biking maven from Portland, Oregon."

"Guests: Loren Mooney is editor-in-chief of Bicycling Magazine. Their May issue ranks America’s Top 50 Bike-Friendly Cities. Eben Weiss blogs at BikeSnobNYC.blogspot.com. He’s a racer, daily commuter, and former bike messenger. His new book is "Bike Snob: Systematically & Mercilessly Realigning the World of Cycling." Heidi Swift is a freelance writer. She writes the "Everyday Cyclist" column for The Oregonian. She blogs at GritandGlimmer.com."
