I've come to believe that with the (supposedly) ever increasing viewership of SX, peoples actual riding 'uptake' from it is cancelled out by the carnage spectators see in it. As in, families being fine and dandy with being entertained by the 'Gladiators', that they largely watch for the crashing etc, but going "f**k no, my little Johnny is never getting on a Motorcycle, Ever".
It's bad enough with Adults (and some barely that - either chronologically or mental age) getting hurt - throw in 'Kids' getting sacrificed to the Lions, and well, things would not be good.
As much as I like seeing the KTM Juniors out there, I fear the day that one of the little takkers get stretchered off with series injuries. I don't think it's happened yet? You can bet your arse that the Media and Powers That Be, will have a field day if that ever happens.
