Located in downtown Rolla Missouri is the Totem Pole Trading Post which advertises itself as the oldest Route 66 business in Missouri.
According to various websites, the business has up and moved over the years, as Route 66 has changed routes.
I am not sure if it’s actually the oldest ……
but I saw that flag when I walked in… I looked around (they were mostly selling a load of highly embarrassing junk… seriously. One wonders how they stay in business)…. I asked the guy if I could use his bathroom, I took a dump… flushed and left….
