A terrible thing.
But a lesson in it. Any fire bigger than a fondue pot don't belong on a table.
Fire pits belong IN the ground. And while you're at it, the grill should be chained so it can't tip over too. And all of it well away from the gathering.
Something is gonna happen. I have been present for a handful of would-have-been disasters in my life. Thankfully, they were never in our midst.
