The first time I got on a bike with a chair I destroyed the hubcaps of three cars on a housing estate as I tried to lean it into a left-hander.
The second time I hit an oak tree while trying to turn right on a dirt track.
Then my Uncle Don taught me to use the bars as a tiller and to steer one-handed - success ! and soon I was getting the plot up on two wheels with confidence
The bike was a Norton ES2 with the rotten plywood sidecar body stripped off and thrown over the nearest hedge.. A friend started the bike for me and my crutches were bungeed to the chassis.
The reason for the crutches was a prior coming together with an Austin 10 which I tee-boned outside the Cricketers Pub in Duncton. Not with an outfit but on a very quick Velocette Viper. This story can be read in The Cricketers Incident
