According to the pictures the location on supercharge.info is wrong. The correct location is 36°06'37.6"N 86°43'26.1"W. Thats just south of the Fifth Third Bank and east of the Kroger Tanning Center. @BlueShift
Supercharger.info has the location slightly wrong. From the pictures the superchargers are in front of (north east of) Yogaworks. At about 34°25'49.4"N 118°33'16.4"W
