Hi Matt
You can get a pamphlet from the state of Indiana about the John Hunt Morgan Heritage Trail which follows much of the route taken by the raiders. There are however, a few places where the Heritage Trail follows main roads rather than back country roads that more closely follow Morgans route. Some of the info I am posting comes from it:
Morgan crossed the Ohio River at the town of Maukport and then entered Corydon, Indiana. A small battle was fought there in which the home guard was quickly routed. Morgan went north aproximately along today's State Road 135 to the town of Salem in Washington County. There the raiders burned the railroad depot and robbed some stores. They then traveled east aproximately along today's highway 356 and or 56 towards the the town of Lexington, which at the time was the county seat of Scott County. From there they moved toward Vernon on modern Highway 3 and then southeast to the small town of DuPont, on modern day highway 7. The raiders crossed present day Jefferson Proving ground to Bryantsburg and then they went to Versailles where the county was relieved of $5000. The raiders left Indiana and entered Ohio on July 13, 1863.

The story has been handed down in my family that the raiders camped on the family farm east of Salem one night and that they appropriated some Yankee livestock for the campfire.
