YES!  WHY DO THEY DO THIS?!  Especially when there is a perfectly good sidewalk right next to them!  And they have the nerve to get mad at me when I pass them on my bicycle IN THE BIKE LANE where they aren't supposed to be walking in the first place!  Oh, and news flash, morons: you're supposed to walk against the flow of traffic.  You shouldn't turn your back to traffic flow unless you're on a raised sidewalk. 😒
