Sullivan County Airport (IATA: SIV, ICAO: KSIV, FAA LID: SIV) is a county-owned public-use airport located three nautical miles (6 km) northwest of the central business district of Sullivan, a city in Sullivan County, Indiana, United States. It is included in the FAA's National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a "general aviation" facility.
Sullivan is so small that it doesn't have a business district.
The context clearly states that Sullivan has a central business district, and my statement says that it doesn't have a business district.  Again I think the negatives are throwing off the system.
