Well, yes, I did, many a time, back in the days when I had a bike.
My most recent one? I gave it away a while back in readiness for my transatlatic translocation. Given the long tedious wait for the glacial gears of government to grind their way toward a visa, I should have kept it for a few more months.
In my childhood days we did not wear helmets, we relied on bone and soft yielding flesh to cushion the impact. But back then I'd never heard of Danny MacAskill, nor could I even imagine the things this guy can do with a bike.
