Bank local, shop local campaign in Illinois
In Death and Life of Great American Cities, Jane Jacobs writes about redlining of urban neighborhoods by banks--redlining meaning that banks wouldn't finance (provide mortgages) in such neighborhoods, for residential or commercial properties, because the location was deemed too risky. Of course, this had deleterious consequences and the communities declined.
She described one area that she passed through as an exception to this, and that's because there was what we would now call a community bank based in that community and they were still lending in their community, to properties and property owners with most of the same characteristics much the same as those being rejected by banks in similar but different communities.
The St. Charles Bank and Trust Company in Kane County, Illinois is running a "Bank local, shop local" campaign at the moment. People who shop or dine in particular zip codes in the cities of St. Charles and Geneva get to put their receipts in a raffle, making them eligible for various prizes.
