Maybe the entire Round Lake area is what's being counted? But then I'm not sure on what basis that would be included. And of course it's weird to include that and not Naperville and Aurora which are much bigger. Very confusing.
I must have tried half a dozen different spellings of St. Catharines, with an e instead of that a, which is the normal way to spell the name. It might be nice to accept what must be an incredibly common misspelling. Or maybe that's the point and you really want people to spell it right, I don't know.
Where is Joliet, Aurora and Naperville??
Aurora IL is at 200K
and don't tell me you don't count suburbs when you stuck Round Lake Beach in here.
