It is the coming weekend June 7/8/9, they did quite a bit of advertising in Chicago, not sure if it is worth to go. Anyone been there know how does it compare to Market Days in Chicago ?

Megabus have a $5 or $9 one way fare sale currently for June travelling on tue/wed/sat, I was thinking to do a day trip there on saturday, the bus fare + admission + shuttle would cost about $30 total.
