C C Hills couldn't even sustain a grocery store for years. There was a Country Market over there on 183rd and Pulaski that closed in the late 90s. They were never able to get anything to fill that space. What they did get across the street was a liquor store, payday loan store, and a dollar general.
North CC Hills serviced by Hillcrest might as well be Markham. Right along with the Walmart, across the street came a cash advance, boost mobile, liquor store and barbershop.
Go to the corner of 175th and Kedzie near Pottawottamie Hills, the shopping plaza, Ariston, and the two gas stations at each of the corners, all have LED lighting with bars across the windows that look like this....
And Pottawattomie Hills used to be nice. Ya'll came in 93 which is right about the time when folks from the city started coming out to the the south suburbs in numbers and when things started to change. So you might not have noticed it much. My mother's side came out south from Washington Park in '69 and left Olympia Fields in '89 for OPRF where home values were more stable.
And you talking about Markham. Markham was still predominantly white up until like the mid-90s.
