Look up

I was walking down towards Picardy Place in Edinburgh at lunchtime today when I noticed a wee sign set up on the pavement by a company called Hawkman Services warning of Abseilers at work.

I looked up and saw this.

I was fascinated but later, on reflection, I concluded that the most incredible thing was how few people noticed which was happening just above their heads .

I certainly wouldn't have had I not happened to see quite a small board with not much information.
