I probably would do the April 1st ASW, only because as a tour guide at a northern UG myself I know that no matter how great the school looks, bad weather can leave a bad taste in one's mouth. I want to try and visit the Northern schools when it's decent outside
That said, wouldn't be too bad to be in Chicago, but I'm not one to enjoy visiting a place for fun without a buddy to go with...I'd get bored easily unless I could catch a Bulls or Blackhawks game, which I wouldn't be able to do based on the train times.
Flights are like 450$ to Champaign, which I think is not cool haha...it's like 300 to go to LA and I'm on the East Coast. Someone wanna loan me a car?
