About this route
The route splits nicely between flat cornfield lined roads to curves and hills on tree lined roads as you near the Eastern Indiana state line. The speed limit is 55 with a few small towns fairly evenly spaced along the route like New Palestine, Rushville, Brookeville and more, but not enough to slow you down too much. You pass by historic towns and sites like the White River Canal locks which were used to raise and lower boat traffic to different levels of the canal in order to traverse the changing terrain. You can also stop and go canoeing in the White River area. I've seen gas stations with horses tied to hitching rails out front on occasion.
The road itself is in pretty decent shape with only a few spots needing repaving, so you can stretch out and ride. Caution should be exercised in the curvy areas as you get closer to the Ohio state line because other traffic can surprise you on occasion, but you can still enjoy the curves if you're not reckless about it.
