I guess the question is the Risk worth the reward?
Let's say the tournament is held and an outbreak results like from the Biogen Conference in Boston. Besides the health ramifications and the tragedy that would result- it would be the end of PGF. The lawsuits and litigation would probably be enough, but even without them would ever entrust them again with the safety of their families?
The Little League World Series has cancelled, probably for the same reason. The health risks and long term financial risks are not worth it
