Whatever you feel safest, if there is a bike lane ride in it. When the bike lane turns into a turnlane get on the sidewalk or your chances of being roadside junk are pretty high. If there is a sidewalk with store doors close to it dont ride too fast or just get on the road for a bit. You are a biker and you do have the right to take a lane when needed, I do not choose this that often because the chances of you being hit are magnafied. Be careful just because you are obaying the law does not mean someone wont hit you.
