I was a locally ranked BMX racer back in the 80s. Last is still a ranking. I was doing great until upon from a medium-sized jump I remembered why I got my Allen wrench and my Kentucky adjustable out of the toolbox before the race. My handle bars folded like a cheap suit.
The bike shop I owned back in the 80’s had a BMX team. I tried riding some races and it was a disaster. When the spectators cheer every time the slightest bit of air is embarrassing. Fortunately my psyche isn’t scarred, my left shin though still has a faint reminder from a Hutch pedal. :)
