Here's a link to the "official" 2004 US Nationals website. I was amused to read that they are conducting tryouts for presenters and sweepers. OK, I can understand that the folks chosen to present the medals - or at least stand around and flank the USFSA officials who present the medals - be attractive and "look" like figure skaters. I did not download the Adobe Acrobat information sheet and application, but perhaps the "sweepers" are the young girls and boys who take to the ice immediately after each performance and "sweep" the ice clean of debris - flowers, stuffed animals, petals from costumes (ugh) and other stuff that somehow lands on the ice surface. I guess these youngsters have to also be reasonably attractive and be able to negotiate around the ice rink.
