No-one is going to enforce the lifejacket BS. What they will do though, is put a death fence all the way along your favourite kite spot, so that if you make one mistake, you will be decapitated by a wire, or knocked out by a 6foot pine bollard.
I guarantee this will kill someone in the next couple of years. Or at least a horrific injury.
It doesn't just affect Cottlesoe either, anyone starting at Leighton who has a kite issue, has horrendously dangerous obstacles should they need to come in before Swanbourne.
