While on my night ride, at around 9:20 pm, I was riding down this longer hill that leads from my house to the center of town. As I was starting to flaten out after riding down this hill a person in a passing car yelled at me to "use the sidewalk dummy". I figured I was fine in the road. I had a flashing light on m seatpost for cars behind me, and reflectors on the front of my bike for cars comming the opposite direction. But the question remains, should I have been riding on the sidewalk? It was my understanding that it was illegal, or atleast frowned upon for bike riders to ride on the sidewalk.
