Indianapolis is known by many names: The Crossroads of America, The Circle City, The Racing Capital of the World, and Naptown. However you call it, Indianapolis is a city of great cultural significance for the United States of America. Out of all the US cities we've been to, Indianapolis is easily one of the cleanest cities. It is poised to achieve significant growth in the next few years, in part due to several endeavours by the city and state to establish several cultural venues, and as part of the city's 'Urban Renewal' project.
