"Hey, The Sidewalk's Fer Regular Walkin', Not Fancy Walkin'!"
However, I can find no reason why joggers around here run out on the street rather than on the sidewalks. I could understand jogging on the grassy median between the sidewalk and the street in order to make things easier on the knees, but forsaking the sidewalk in order to play in traffic seems more like a pathetic cry for attention. Kid of like those kids that drive back and forth on your street, bass pumping, in the desperate hope that somebody will notice them.
That's why I really don't feel any regret when I run them over...Jerks!
