In this post I commented that I was not sure what the Eisnehower Interstate System was and that I would look it up.
In short, it is the interstate system of the United States. It is called the Eisenhower Interstate System because he is the person who made it happen.
The Eisenhower Interstate System has been called "the greatest public works project in history."
It seems like something interesting and something to look into further. ;)
More fun on the Eisenhower Interstate System soon I am sure.
