Go on a highway tour through Duluth and learn some interesting facts on the way. 

Youtuber 18keithb likes the roads, I'm only guessing because of his videos have to do with roads, He got out his dash cam and drove through Duluth and pointed out things on the way.

He started by Thompson Hill and ended going on the bridge towards Superior. Check out the video and maybe you'll learn something new about the highways in Duluth.
