Critical Mass started off as a leisurely bike ride in baltimore. Then, a car decided not to share the road with the bikers and hit one rider, bending his rear wheel. After the police showed up to do some in-depth special police work, another accident occurred when a pick-up truck avoided the bike/car accident and hit a van with its flat bed extension. The van got a flat tire. So the lesson learned today... share the road with people on bikes, or just get out of your car and ride, ride, ride. No cars, No car accidents!
