There is a greenway I ride through for about a mile on the way to the afternoon rides from my house -- only other choice is a narrow one lane road that is all door zone all the time (plus drivers in my neigborhood suck). This greenway has a specific lane for peds RIGHT NEXT to the lane for bikes, but still families and their kids meander unpredictably in the bike path. My favorite is the mom's who let their kids ride their big wheels unsupervised -- that is a disaster waiting to happen. Of course the pathetic bike cops do nothing . . .
