Sometimes people ask me: "What is the strangest thing that has ever happened to you, as a taxi-driver?" It is difficult to answer. But one of the funniest things that ever happened to me was in November 1962, the year of the Great Fog.
Foreigners always thing Britain is covered in a blanket of fog every winter from October to March. It is not really so. But in November  and December 1962, we did have some bad fogs in England.......   The first  night the fog came down very studdenly.I was driving someone from Piccadilly
 to Richmond. I took my usual short way through Richmond park. It is a nice pleace - quite wild, with clumps of big trees, ponds and herds of deep. At week-ends people go there for picnics, fnd every evening men go there to run. To run? Yes -men practising for cross - country races."Harriers", they call them
Well, we overtook a group of these harriers, running through the park.
"Not my favourite sport", I sade to me fare.
I left my fare at her house and went off again for London. Out of habit, I turned  into Richmond park again. I soon understood that I was wrong. The fog was really thick. The father I drove into the park, the thicker the fog became. I switched on my fog lamp. It did not help much.
