Boy, I know what you mean. Here in NYC, joggers and other pedestrians have all but taken over the Hudson River bike path - even thought there's an adjacent pedestrian path that in many places is much nicer and right on the river. Even though I know I shouldn't, I sometimes go off on these runners, especially the joggers with iPods stuck in their ears who drift or turn into my path. I have seen dozens of accidents on the path and been involved in some incidents (none serious) myself, and nearly every one was caused by a jogger who did something unpredictable and was where he shouldn't have been. When I go by a particularly clueless pedestrian - one who is running in the middle of the path or wandering all over the place - I'll yell, "Natural selection!" at them. I know it doesn't do me any good, but it makes me feel better. Lately, I've been seeing joggers pushing their babies in carriages while running on the path. Nice! Nothing like risking the life of your kid while running on what is essentially a bike road. What angers me further is that there is absolutely no enforcement of the path. Yet, if I were to set one wheel on the pedestrian path, pedestrians and park police would be all over me (I've seen it happen).
