On: A walk through Chicago Pedway (2017)

[dang]

We've since changed from the submitted URL (https://www.chicago.gov/content/dam/city/depts/cdot/pedestri...) to the article platz suggested (https://news.ycombinator.com/item?id=39351010).

Wikipedia submissions are fine if there really isn't another interesting article out there, but we prefer a non-generic source where possible.
