Lack of cool? The home of the Crown Point Jail that Dillenger broke out of with a gun carved from soap? Gotta second that Indy’s a (what’s a nice word?) shithole.
I’m a Chicago area loyalist and a former resident of Eva Luna’s Arlington Heights (Arlington HS class of '72!) and can recommend that highly. There’s this big Japanese grocery store on the south side of town where you can get ripped off in a very nostalgic manner. The far-west burbs where I am now can be pretty but also pretty expensive. You can live in Lombard, like me, and take advantage of the good points of living in a VERY wealthy county but pay less for housing than just about anybody in a liveable part of Chicago with none of the negatives. Except, of course, the weather but after your time in Japan you’re about due for a climate. And O’Hare is a hop, skip, and only half a jump with (I assume) tons-o-non-stops to Japan.
One thing about the Chicago area versus small town anywhere is that you can get any kind of food you want. ANY. Friends who have moved away come back here not to see me but to eat. (this is where drop starts playing dirty) Remember Italian beef sandwiches? Decent hot dogs? Pizza? Then there’s the ethnic food. Representative of every ethnic group on Earth have moved here and opened restaurants.
