I had 8 seniors on one team come to the captains meeting. that was nice for them. But in general, I think it would be like going to the dentist for fun. I've been to some as a R2 where I just wanted to say "will you shut up and flip the coin!!! Really, do you need to tell the players where the lines are on the court if there is not any unusual interfering lines? Why don't you tell them how much air is in the ball or how high the net is?
