The road to the 2008 Democratic National Convention was paved with freebies. Free meals, free parties, free stuff, free bags to hold said free stuff. Of course, 99 percent of it was useless (the windmill lapel pins given out wouldn't even look good on Al Gore), but there was one display of killer, if temporary, swag: a thousand free bicycles, courtesy of the Freewheelin bike-share program organized by the convention host committee, Humana Inc. and Boulder-based Bikes Belong. Thanks to the crowds and the beautiful weather, the slick new green bikes were the coolest way to get around. In fact, the city was so taken with the idea that it plans to unveil a similar bike-rental program this summer. That's change we can believe in.
