I have been to Chicago as well! I will say though Chicago is a bit of an outlier though - it is technically the midwest but its also not entirely culturally the midwest either

People are definitely community oriented there - theres alot of polish community events, open friendliness towards sports outings and open pickups (basketball volleyball etc)

I will say though I think in Chicago it tends to be a bit more like clique-y though - culturally and sportswise comparitvely to something like NYC.

Like in NYC theres alot more international / individualism though, in Chicago the city itself enforces a good number of rules on what you should and shouldnt be (example is the pride colors painted in boys town)
