What are you smiling at?!?

Do you ever notice when you are driving there will be people running on the side of the road, completely ignorant to the sidewalk two feet from them? Why? Are they that unhappy in their lives and feel the need to risk death by running next to cars traveling at speeds up to 40 mph? Not only that, but most have their headphones plugged into their ears; they might as well be deaf. Not only do they cause a distraction in the road....i.e. an attractive male or female, but they cause you to slow down, steer around them, avoid on coming cars....etc. Just do us all a favor, use the damn sidewalk. It's just as good.
However, if they feel inclined to live life on the edge and use the street to exerise in versus the perfectly functional sidewalk that state workers spent days on, slaving over jack-hammers, cement mixers and leveling tools, well then by all means---go right ahead. But you won't hear the last from me. Same goes for you bicyclists!
