Wyoming Public Television made an hourlong documentary for the centennial of the Lincoln Highway in that state. It won an Emmy.
It’s entertaining and informative, and I’m going to link to the station’s page with the video although I first saw it on YouTube. (It was what inspired me to make a blog post last Thursday, and how I discovered things were bad.) Among the topics the documentary covers is why and how the route got signed through Medicine Bow, while I-80 passes far to the south today.
