Yes, Virginia, there is Winter Biking!
Tips from Winter Cyclists
"I'm no cycling guru whose blood has been thickened on arctic expeditions. I'm just an urban bike commuter who, through experience and advice from friends, has gone from being a fair weather to all weather cyclist. The process was gradual. The first winter I didn't invest in special gear; I just piled on what I had. I learned how to ride in a range of weather conditions simply by doing it and watching my friends. Winter biking isn't something difficult, something you need to equip for. The only equipment you really need is the willingness to do it. - Gin Kilgore "
