I encourage parents to drag their skate kid to watch an adult competition. Your kid may be bored that the adults don't do many fancy moves, but the competition will surprise you and is in your long term interests.
Adult competitions are very laid back. The technology is old school, with clipboard scoring and volunteer runners like a local competition. You'll spot the older members of the usual rink crowd. Compared to the real (non-adult) sectionals, the Adult sectionals is easily five times more relaxed. Despite the nonchalance the competitors themselves are pretty urbane about the whole thing, knowing everything involved to nab a ticket to Nationals. Still it's well past time for nervous excitement; it's like being in love for the sixth time.
More than any other skating group the Adults display an extremely wide variety of skating approaches. They show as much variance in their style as the juvenile division, plus everyone skates different elements to boot. Their music is completely all over the map.
There seems to be a fair amount of tongue-in-cheek emoting at Adults. They are well past the age of taking themselves seriously and can't hold a candle to the physical strengths of the younger athletes; the crowd is both well aware of this and is also in on the joke.
Most of the competition's psychic value is sublime -- since the skaters are adults they have full lives besides skating. Real-life art hides somewhere between the adult skaters and the competitive youngsters. Or to put it differently, the art of life happened in that region in between, where it became impossible to skate. And some of this seeps through to the other side.
