I'm looking for twisties and scenic drives between and around Dayton and Columbus. We have a wonderful SE section to our state, but is there any ponts of interrest on our west side? I am trying to find something to entertain a small caravan of NSXs on our drive from Columbus to Dayton in October. Was wondering if any body here knew something that I didn't.

 

I only know of roads in the area of, if you form a diamond, between Springfield, Troy, Bellefontaine, and Marysville. Sorry, i don't know anything that is on the south side of I-70.

 

there is a set of twisties that follow the miami river between sidney and piqua that is the only thing i know of and it is out of the way going from dayton to columbus the road name is miami river rd

 

I agree. That is the great flat lands. Follow river valleys if you want curves. That's why SW Ohio is good in many areas. Ohio river, Great Miami, Little Miami and all the feeders. Those rivers and their tributaries create all our great driving in Cincinnati. Otherwise you don't get shit till you get several counties east to Adams county.

In the area you are looking, follow the river valleys since you are north of the glacier line.

 

Not familiar with the area, but this could help.
