Colin, that reminds me of a chap in the RAF who used to ride a motorbike a bit fast, whilst indulging in this pastime over a very hump backed canal bridge on a narrow country road where he would try and improve the distance he was able to remain airborne he was somewhat disturbed to see a large number of cyclists in his path, luckily they had sufficient warning of his approach to peel off into the hedges on either side, he thought that was a great hoot.
A few weeks later his fiancé dumped him, so, with the money from the returned engagement ring he bought a Vincent 1,000cc, within a few more weeks he lost an argument with a lamp post; one of the never learn types, both parents and his brother had been killed on motorbikes; being the only one of the family left, his sister finally got the message & sold her bike.
