Downers grove is a lovely town, my home town. My mother’s too. Very safe, good schools, library, parks, nice little restaurant scene that has grown steadily over the last 30 years or so.
The train is great to have, there are express trains to the city that take about 35 min, and normal trains that will get you to union station in 50 min or so. Trains also bring some strange people sometimes, but it’s hardly a problem.
A tornado touched down by my parents house in downers about 30 years ago, destroyed a massive tree, and did some other considerable damage, but from what I’ve heard, the likelihood of a tornado in the whole Chicagoland area has decreased as the climate has changed. Can’t say it won’t happen again but it’s unlikely.
A lot of polish people moved from the city about 50 years ago to downers grove and other nearby suburbs, but you likely won’t find too many polish speaking people anymore, just people of polish heritage.
Another one of the long time posters here is from there. Wish I could remember who. Never really talked to them about it just noticed it in their location.
