I'm in the far suburbs of Chicago, but I wasn't aware of this, and it does look like there's one of these in downtown Chicago: https://www.chicagohash.com/

Downtown Chicago is a bit far for me to drive for a run, but I'll keep an eye on it in case one of them ends up a bit closer to me. And maybe this will help someone else that does live downtown. Thanks for the suggestion!
