If bicycling is lots more than a sport for you, you're probably part of the bicycle culture. Did you know there's a magazine edited with you in mind? It's Momentum, the magazine for self-propelled people. I loved it as soon as I started reading, because it covers transportation cycling so well. And if you subscribe ($15) through this link -- www.momentumplanet.com/advocacy-subscribe -- the publisher promises to make a $5 donation to Green Mobility Network. You'll see an alphabetical list of bike-advocacy groups the magazine cooperates with, and we're in there.
