The whole multi-use trail thing rears its ugly head again (check the forum and you'll find dozens of threads on this topic). As runners and cyclists, my wife and I have seen both sides. We've cycled past the runners that have zoned out and are running centerline and we have been the runners when road bikes zip past and have not given enough berth in their passing. Both experiences are similarly aggravating. Like many things in life, it comes down to an us versus them type thing...the only problem is some of us are them.
