Someone keeps dragging several huge black bins onto the cycle lane on Middle Meadow Walk (the flat section between the crossroads and Marchmont). They're the big residential street bins, only without lids. It's happened at least twice this week so far. Because they're a very obvious hazard to cyclists - right on the cycle lane and big, black & solid with sharp edges - I've stopped and dragged them off the path every time I've encountered them.
I'm going to get fed up of this quite quickly, so can anyone suggest what might be going on here or what to do next - for example is this being done by vandals trying to cause a bicycle crash, or is it being done by some cycle-blind bit of the council?
