It's funny the things you learn while on a roadtrip. Don't have a clue what's happening back home but you get to learn stuff like this.
I guess if you were ever picked to be on a game show, information like this might be useful, I don't know.
But I am thankful to Dwight D. Eisenhower though. Can you imagine how long we would be gone if there were NO highways!? Thank you DDE!
