WFMU radio's Cosmic Cowboy devoted a couple of hours discussing (RealPlayer) with a bunch of participants the crackdown on last year's Critical Mass bike rally in Manhattan. This story got buried amongst all the other strangeness during the RNC.
This site has a bunch of Resonance FM radio shows devoted to biking archived for your amusement. Very clever, as they record some of the shows during real excursions around England. Who needs Click & Clack?
