Never tried a reverse steer bike but I was banned from trying the unicycling at a local fete a few years ago, as I could ride it perfectly well. The stall holder was tipped off by an Aunt
"My Niece can ride those really well, that's her in the red top over there doing archery". When I went to try and win a tenner for riding a unicycle 15 metres I was told to 'sod off'. Charming.
I was also banned from the 'darts-archery' stall. After putting 3 arrows in triple 20 at 25m with a rather tatty recurve. He asked if I'd shot one of these before and I told the truth, I said 'no'. I failed to mention that I shot Longbow and Compound (was that naughty of me). I had 3 'sighter' shots before the 3 shots that counted. I put 1 arrow in the outer ring of the bull and 2 arrows in the inner ring as 'sighters' and then did my 180 thing. Stall owner did not look happy as the score to beat was one of his pals. Poor chap had to go out and buy a bottle of Champagne, as that was advertised for the winner.
We saw him at a fete a week later and I was told to 'go away' in no uncertain terms.
