I am wanting to buy tickets for the Ladies Free Skate and possibly the exhibition(or if I can't get Ladies FS tickets then I'll probably try and get the Men's)...but I don't want an all event ticket(can't afford it). I see that they are separated into sessions and the pre-sale is 8/27. How do you know what sessions contain what events? or are the "sessions" the practice sessions? I've not been to a US Figure Skating Championship before...so I'm not sure how it all works.
