Surely the big failure here is the decision to use "concept" netting in a live tournament, not the weather. Any decisions made after the netting failed were just damage limitation. If 'non-concept' netting held, then it's not enough to blame it on the weather...
Actually, I've just got back, and the Div3 field (with standard poles and netting) had also suffered the brunt of the weather, with 2 poles on the end of the field completely buckled beyond repair and the netting down with it during saturday. Many of the other poles were also visibly warped and bent.
We spent a little time in the Joy pit whilst they were waiting to see what was happening on Saturday and the staging area tents took off whilst we were under them, again, about 8-10 of these were pretty much destroyed by the wind (and they'd already taken the canvas off most of them!)
People were wandering round with goggles on simply because so much sand was being blown about and I got the impression that the only reason everyone was kept in the dark about resuming play was to keep the vendors happy and keep everyone milling about and potentially shopping.
In fairness to Millenniums, play couldn't have gone ahead regardless of the bouncy castle/standard netting issue, but more could have been done to keep the players in the loop. They did work all night to get the fields re-laid however and you've gotta respect their staff for the work they put in to try to keep the event on track.
