The sun's starting to set a little early and the kids are back in school. And while you hardly need an excuse to Bike Fall, you might need a little motivation to Bike Winter. Bike Winter is a site that provides lots of info on how to dress for cycling when it is cold out, as well as staging lots of events. Things officially get started on Oct 1st, but the planning is happening now if you'd like to lend a hand to make Chicago the best city in the US for bicycles.
