One of the things I enjoy when cycling is to come across a change in the road. One of my favorites is a water ford where the road dips down below the water. While these are interesting you do not want to ride through one. Even if there is no water flow the surface is almost always slippery and rough ending up in a nasty fall. Ferries are my next most interesting points of interest. Initially the only way across a waterway,unless the water level was down, was using a ferry. Ferries were numerous across the country. Covered bridges round out my interest in road surface changes. Bridges initially built out of wood quickly deteriorated leading builders to add a roof to keep the wood dry hence preserving the structure. Covered bridges also have hidden hazards. The wood tread looks inviting however most of the treads have wide cracks between the planks which easily catch a narrow bicycle wheel and almost always causing an accident.
So as interesting as all of these are it's best to dismount, walk the bike and enjoy the change in the road and scenery.

Qualifier for these routes!
The following routes were developed over years of biking in Indiana and now Kentucky. At the time they were the most direct routes using paved county roads and minimal secondary highways to connect the county roads. When possible the most scenic road was used. Over time most counties added more paved roads however in a few instances when county budgets were stretched, roads reverted back to gravel. Using my routes you'll almost always find that the distances between two points is more than taking highways however the scenery is most often better as well as the traffic. Hopefully you'll enjoy the great cycling in Indiana or Kentucky and if possible provide feedback on your trip.
I am not making any recommendations nor can I say that these routes are free from road hazards or dangers from traffic. Users of these routes will find them scenic and remote however only the user can assure they are safe on any public road.
