Who's Turn to Dig?

Workmen have appeared this week and are slowly digging holes along the road. Thought they seemed very colourful, what with their jackets and the fences. Holes seem to be appearing every 100 metres or so, each surrounded by a square of gaudy fences.

I have been trying to think of inspiration for this weeks Challenge, 'Body Parts' without much luck. Had it been sunny and warm today perhaps I would have found a suitable 'body part' blip from my workmen!
