Hi,
Tragedy! But avoidable.
I'v been around families with kids near a large spontaneously communal fire and really have a hard time not interfering with potential accidents I see, just waiting to happen. Their kids are their business, not mine and some can be very protective of that.
Pools have rules like "no running", "no jumping" etc, and they are much more forgiving than hot coals and flames.
It seems some parents are oblivious to the potential of kids running excitedly between adults and the fire, chairs and the fire and generally behaving like the fire is a nice warm benign happening with all the danger of an innerspring mattress.
If it is an organised trip, with a trip leader, it is so much easer to gather the parents and kids as the fire is being lit and run through the 'rules' and involve the kids in answering why we have the rules and what could happen if the rules are ignored.
Cheers
