what part of the country is the closest to a feudalist system?

[Filuwaúrdjan]

Nowhere.

Feudalism was all about exchange between different estates in an ordered society; I'd be amazed if something like that has ever existed in the area covered by the U.S.A. Of course the word feudal is misused almost as much as the word fascist.

Of course you could certainly have had serfdom.
