Crap in this instance.
No-one should ever wait for a tragedy to happen 1st, before improvement is made. I recall an accident like this happenning in the early 90's @ the ground - but a car, and hitting an adult.
You say: But to blame anyone for a truck running off the road into a queue of people is absolutely ridiculous.
I say: not ridiculous. That is why laws have changed Fro. To alleviate or mitigate the risk in the 1st place, or BEFORE it happens.
Like I say, if one of your loved ones gets run down, burnt to a crisp, cut to ribbons, breaks a leg on the downside of the hill etc., I hope then you realise your argument is flawed.
Additionally, check all the media releases from the club about the ground Fro. MOST stipulate that a 1st priority is changes to meet minimum safety guidelines.
You can argue your ridiculous statments as much as you like, the fact is we need funding, or something unfortunate may happen (maybe to you !), and the changes or funding assistance will then be way too late.
