Ugh. A city full of people we can't stand when the Yankees are in town? Nah, I'll pass.
They suck.
SG you'll like Chicago. Don't listen to Weber. Not enough trees here
I think it's reasonable to be skeptical of someone liking Chicago if they hate NYC. Obviously there are key differences, but most of the reasons why people would hate NYC can be applied to Chicago in some way as well.
But it's hard for me to fathom anyone hating NYC that just doesn't dislike big cities in general.
