Going to Columbia would add time and distance. It's supposed to be a cool place.
Hermann is also a bit of a side trip, and is also supposed to be fun.
If you aren't overnighting in Jeff City, at least ride over to Central Dairy and get ice cream. You get to ride the big spiral ramp and see the capitol up close. Plus, ice cream. :)
We skipped the winery side trips, but those also add time and distance.
