I found a page on it as USFS. It has some of the rules, looks complicated. One has to apply for permission. There is a warning about paid performances messing up college scholarships under collegiate rules, which allow NO money for performance. So, that would be a factor if someone were to get on a university team.
I see the hockey kids selling raffle tickets at the hockey game to raise money. Hockey scholarships are more common, so I guess they really steer clear of skating to raise money.
I just had a quick thought of some of our really good girls could skate at hockey game intermission as an exhibition, while the score board has a link for donations to the skating club or tells of a raffle table where spa/lady type baskets are being done. It's really hard to promote the sport and the local club, if you can't show off!
