Ever wonder how they clean the windows on a 35-story building? Let’s just say not much has changed in the past 50 or so years; a plank of wood (otherwise known as a Bosun’s chair) with a few straps, some rope, and a bucket with tools. Freaky!
I am not one who is usually put off by some life-threatening thrills in semi-controlled circumstances but hanging off the side of a building on a piece of plywood is very low on my list of desired activities. If it were a climbing harness, on the other hand, I would be all over doing that.
And a few commuter bikes for good measure.
