Starting on Business 41 in Vincennes, head north of town to the turnoff to IN67. Follow it through small towns and farmers fields to Spencer, Turn onto IN46 east to McCormick's Creek State Park just east of Spencer.
The further north you go on IN67, the more fun it becomes. You start in the valley of the Wabash River going through several small towns and farmer's fields. The road begins to get more into the forested hills about 20 miles outside of Spencer.
The road conditions are excellent, although we had a small detour of a couple of miles for bridge repair at Switz City. It's a smooth paved secondary chip-seal road with sweeping curves. It's obviously an older road when you get passing lanes every so often. If you're riding for thrills, it's not all that great, but the gems are in the things to see at each end.
The town of Vincennes has a lot of history dating back to Revolutionary War times. The National George Rogers Clark Historic Site celebrates his small band of militia that helped to cement the Northwest Territories for the US. It overlooks the Wabash. Also in town is the Indiana Military Museum south of downtown and the Red Skelton Museum of Comedy on the Vincennes University campus in their Performing Arts Center celebrating his hometown and his multi-faceted personal history. Traveling up IN67 past Spencer is the rustic McCormick's Creek State Park. They have cabins and a lodge for overnight stays. Take in Vincennes in the morning, spend the night at the state park, and head on up IN67 to Indianapolis for night life or ride the backroads of Munroe, Morgan, and Brown Counties if you stay on IN 46 east.
Motorcycle Road Additional info
Amenities are available at both ends. Vincennes is a fairly large town with lots of service stations, restaurants, and lodging (it's a college town after all). Spencer also has gas stations and a selection of franchise restaurants, but the town doesn't have much lodging (hence the state park).
