I remember getting hit in the shoulder by a flicked up stone on the M4. It was only the size of a large pebble, a bit like the stones you see in the hard should traps. It hit me on the rubber armour. I was wearing an AlpineStars GoreTex jacket. When I took my jacket off you could see a bulls eye mark in the armour it had hit so hard and marked my T shirt underneath. I was doing about er hum mmmm 70 plus .... that always reminded me how much damage it could have done. That one on the lorry was at least a leg breaker !
