Winter biking is safer than you think because you ride slower - all you need is to use some common sense and follow a few tips for a safe warm trip. The hardest part is making the choice to head out the door and get on your bike. It only takes a little pedaling to warm you right up.
No windshields to scrape, no hunting for parking, it's free, and you are doing your part to save Missoula's air quality. You may even get where you're going faster than driving, and more alert and in a better mood (yeah endorphins)!
It is not uncommon to fall over at least once if you are biking in winter weather. If you do fall, try to go with the flow and roll with it- don't try to put all your weight onto one body part!
