Steve,
Your definitely not alone in your observations, and the club is well aware!
Your totally right, carnage is only word that can accurately describe what goes on in that heat sometimes, so we will try and do something to rectify it accordingly.
I guess the challenge for us as a club is try and promote the sport to the next generation as much as we can, but without then taking the fun out of it, and alienating them, as I'm sure you'll agree.
The balance is there to find though, and we need to find a way to make our vital new comers both aware of the rules, the etiquette and respect needed to 'race' AND keep fun at the core of it as well.
Maybe the best thing we can do would be to instate regular race briefings, and gently instill the basics of the rules each week, or at least regularly, and see how that goes.
When its one or two mixing with the 'grown ups' it seems to be fine, but when a lot of younger newbies race together the respect and general race craft def goes out of the window!
Leave it with us, see what we can do
