You could look on their facebook page. I know you usually do the amateur freestyle. but I don’t think they have it because they didn’t have it last year (I was there).
The 2014 Illinois State YoYo Contest will be on November 22nd not ON Navy Pier, but inside during the Toy and Game Fair. It’ll be my third year going, and it’s always a great contest. The divisions will be 1A (prelims), Dual (2A,3A), and Aerial (4A,5A), along with sport ladder. Usually, the only vendor is Cat and Mouse Toy Store (http://cat-n-mouse.com/ocart/), but they have yoyos of different brands. I guess you could say it’s like a smaller collection of YoYoExpert.
