Have you heard of the team sport,  Ultimate? 
Oh yes, I love Ultimate! Do you play often?
Not as often as I would like.  I thought it was a new sport, but it was developed in 1968 in New Jersey. 
Wow, that's fascinating! I always assumed it was a more recent sport too. If it was more warm where I am I'd love to play more, sadly it's too cold so people don't want to play!
Well, I'm in Florida and it is very hot here, however, I hardly get the time.  I really love how the sport is based on sportsmanship without referees.
I love that aspect of it too! It feels so different from other sports, but it really works! Are there any other sports you know that are based on the players morals? I can't think of any
Not many.  I suppose golf focuses on self-officiating where players maintain their own score cards for fair play.
