Grab some popcorn and watch Dan Burden give one of the keynote addresses to the Louisville Bike Summit. He explains in stark detail why bicycling benefits not just athletes, but the entire community. MetroTV has the clip.

Note: Dan is the third speaker. The first speaker is Andy Clark from the League of American Bicyclists. The second is Mayor Jerry Abramson. The third is Dan, and he'll probably be of the most interest to cartky.org readers, though of course they're all good.

Hat tip to Bike Louisville.
