Wasn't this at the Pheasant run resort last year? I went to one that i swear was the same name. Mostly vendors to answer questions and sell stuff, there were few tech classes you could sit through,i believe one was on carb tuning and maybe a nitrous tuning class. I bought a 5 gal fuel jug and collected stickers.
It was like a mini pri show. Had a little car show thing in another section. Hopefully the Schaumburg building is bigger.
