New Poster -and a Question

Howdy - I've been reading the forums for a few month and decided to take a dip in participation.  I enjoy making sourdoughs and baguettes.  Anyway my question...

Where does someone find a mill with fresh Flour?  In the books I've studied they say fresh milled flour is the best, well I can't seem to figure out where to find these guys to try it out.  I live in the Midwest about an hour and a half east of Chicago.

Any help would be great.
