It's stupid, I know, but that is the name of this thread after all. I get pissed off at pedestrians who insist on walking in the exact middle of the bike/ped-path on their way to work. Gaggles of kids are excepted, they don't know any better and are too busy goofing around to pay attention. But grown people walking alone on the same path every morning being passed by bikes should at some point grasp that they are in fact on a shared path, a large one, and that those passing cyclists are a lot less intimidating if they would just pick a side.
