Geography Lesson of the Day

Since I just had to look up all this information and inform a certain friend of mine, I figured that I would inform the rest of you.

There is not difference between a state and a commonwealth. Only the name. There are 4 commonwealths in the US (Pennsylvania, Virginia, Massachusetts, and Kentucky)

People from Guam are in fact US citizens and people from the rest of the US do not need a passport to visit Guam.

I do not, however, know why it is called the Midwest and not the Mideast.
