Sort out of relevant to this thread is the following from a bike shop owner:
One of my regular customers recounted this, the other day; he’s in his 80’s silver grey hair, cycles all over the world.
Anyway the other week he was cycling up by Achnasheen,(single track roads with passing places), when a car passes him, and the driver offers words of encouragement: "Going well young man" etc
Some time later, he can hear another car behind him, this time the horn is sounded. Then, It’s sounded again, a little louder. So he twists round, and gives them two fingers. The horn goes again, So, he sticks two fingers up again.
By now he’s now shouting. "I can’t make myself F*&!#ng Invisible !"
So he pulls over and the driver gets out the car.
It was the same guy, who had given him the encouragement. He had returned with a lunch pack he’d just made up, including cold drink wrapped in an ice pack, freshly made sandwiches etc.
