St Clair, MO
The ride from Gray Summit passes through Union, Missouri MO, where you will find Bourbouise Harley Davidson.
Avoid the Indian Harvest Trading Post. The people who run it are nasty. When I pulled in to take a picture and tell the owners about my Route 66 website, I was met with a violent shouting outrage that nearly came to blows. I have never experienced anything so hostile on Route 66, or anywhere else for that matter. Others on the internet report similar experiences. Local shopkeepers say it has some nice merchandise, but they won't recommend it to travelers for fear they will have the same kind of experience I had.
I just read a review of this place dated March 24, 2022. It said "They assault their guests. Don't ever go there."
St. Clair itself is a pleasant little town of about 5,000 residents. It has two water towers labeled "Hot" and "Cold".
