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. :)
I've had a couple of spectacular wipeouts on my BMX bikes. Neither were on the track. Both were a conspiracy of lack of coordination, gravity, and a juvenile disdain for the laws of physics. Only one resulted in a trip to the doctor to remove chip seal shards and tar from my hands and knees.
The other resulted in my neighbors wondering if my family had gone mad as my dad came out the door and asked me to repeat what I'd done because he'd missed it. They even asked if I was okay as I was sitting on the street bleeding from my hands and knees once again. But no tar and chip seal shards this time. It was funny thinking about it. About a month later.
