There's a Bikerfest September 18 - 21 at the Bill Monroe Campground in Beanblossom (yes, Beanblossom!). It's on State Road 135 just outside of Nashville, I'm planning on Saturday, probably around noon, anybody else around Indy, or where ever like to meet up?
For some reason, this part of IN has a lot of interesting town names; Gnaw Bone, French Lick, Hornettown, and the roads in Brown County (curves and hills) draw quite a few bikers.
