Looking for advice on special roads to drive, etc. In a couple of weeks, I'm driving from Frederick MD to Madison, WI for a week-long training, then will head to Ft. Madison, IA to see family for about a week, before heading back. I have about a day and 2/3 to get to Madison, but on the way back from Iowa I plan to at least follow the Ohio River for a while, so plan to make the return more leisurely.

Understand that Ohio Rt 26 is good road - what are the beginning/end points?

Any help is appreciated.

John
