As has already been mentioned, those public tracks are all good. Within 45-50 miles of Indy is some other great public tracks, i.e North course at Purdue Kampen GC, Rock HOllow in Peru, IN owed by Chris Smith's family, south of INdy Otter Creek in Columbus a 1960 RTJ Sr. course, Harrison Hills in Attica, IN has some interesting holes. Send me a personal message before you come and if I'm available, I host you at my home course, Wolf Run GC. Other privates if you have some connection and access, Crooked Stick, Sagamore, Bridgewater are the best.
