North Dakota had three or four offices around before the modernization of NWS came around. Today, I'm served by Grand Forks (15 minute walk from my dorm room
).
Originally (and I'm not sure on this; trying to remember what a NWS friend of mine told me), we had an office in Fargo, one in Bismarck, and one in a tiny little town called Williston. You may know that town as where ND has had its recent oil boom.
Anyway, when modernization came around, ND was put under total control by Bismarck (western and central ND) and Fargo (eastern ND and northwestern MN), before Fargo relocated from the Hector Airfield and moved to Grand Forks, on UND's campus. Ironically, the Williston office is still technically in service - there are only two employees there that man the phones. We have no clue when it will be shut down.
