I've noticed recently that there is a special sort of fool who has become more common around River City: Grown men on bicycles wearing helmets while riding on the sidewalks. A couple of things. First, whatever argument there is for a child to wear a biking helmet (not much) or for a contestant in the Tour de France (admittedly some) is no argument for a 35-year-old man be-bopping through the city. You don't need to be a Hell's Angel to dispense with that piece of plastic atop your noggin. Second, no one over the age of twelve should be riding his bike on the sidewalks. Those curb cuts at each intersection are for the wheelchair-bound, not for helmeted adult males who need to grow a pair. Get your bike out onto the street! Better yet, walk or drive a car.
