Hello Everyone

I started biking in June after a long period of fear. I am riding my bike to work about twice a week (10 miles) and getting a ride home with my husband (we work together). I am wondering, how many people here have been hit by a car, or hit a dog ( both for me), and what are your philosophies for staying safe on the road? I always wear a helmet and now I am riding defensively. Do you use a mirror? What kind of legislation is out there for bikers? Are there bumper stickers I can get for my four wheeled vehicle? Strobe lights for my bike? Thanks to all for responses..............Leigh
