Sure it might be an inconvenience, but who ever has made the decision would have done so with consultation, it is their right and their responsibility to make the call. I understand some noses may have been put out of place (so to speak), sure, some people may be disappointed but it was obviously decided it was in the communities and states best interest, that Volunteers protect, to cancel the competitions.
Think about all the crews fighting fires currently that can't attend anyway as they will still be on strike team deployment. Think about what we have seen over the last few days, which if occurred again would have occurred in areas which were under-crewed due to people being at the competitions.
Unfortunately, sometimes "IT" happens... Just look forward to next year and hope the fire season won't shape up to what it has displayed in the last few days.
