Tutor/Mentor Connection web library and found a site that allows you to map locations of different businesses in different geographic locations.
I created this map, showing banks in Chicago on the near SW side of the city. If you were operating a youth program in this area, reaching out to these banks for volunteers, board members and donations would make sense, since they share the same geography and its problems and opportunities.
Using the site you can create maps showing a wide range of businesses, not just banks.
The site was not created as a resource for non profits, but instead to support small business development. However, I think creative non profit leaders could use it the way I've described.
Visit the site, click here, and make your own maps.
