I assume you mean Indiana, not Indianapolis because I am certain there are no "Dragon" type roads in Indianapolis. I am not the guy you are refering to, but I have been living and riding in Southern Indiana my entire life. Actually, there are some decent roads down here, although it would be quite a stretch to compare them to the Dragon.
Most of the better roads (twisty with elevation changes) are found in the Southeastern corner of the state. Beleive it or not, there is a highway 129 in that area that is a lot of fun (no Dragon...maybe a Salamander!). Also 250, which runs East and West, has its moments. 56 & 62 are decent rides as well. 150 From Shoals to Paoli has some nice turns also. The most famous road in Southern Indiana (made a write-up in Road Runner) is 135 which runs all the way from Indy to Kentucky. It runs through Brown County, Bean Blossom (former home of the Abate "Boogie!"), Nashville, Story and all the way to Corydon - Indiana's first capital. It is a nice ride. I would be more than happy to share some more detailed directions or take you around some time.
