As a former marching member (loooong ago!) and parent of a kid on the field now, I don't believe stopping the performance is the right thing. I think the risks outweigh the benefits. The keys lie in a couple of places. First of all, these days, kids fall down. Much more than BTID. Anybody that remembers the "domino effect" of Garfield 1984 in Whitewater knows its happened for quite a while, but the demand put on marching members today is crazy. Plans need to be in place for such things. Members need to be TOLD what do to if... Secondly, the staff has a crucial responsibility of watching the show for signs of trouble - maybe not teaching staff but perhaps volunteers. Knowing the level of difficulty increases the chances of weird things happening means a plan should be in place...its not like the difficulty level is going to get easier! Finally, the fact that that judge pretty much walked on by had me YELLING at my TV last night" If that was my son that lay on the field like that, I can assure you, I would have gone ballistic!! Again, a general plan must be in place for emergency situations like this.
Bottom line, the 'grownups' need to think ahead so kids are protected as much as possible!
Ok. Rant is done. ;)
