GTA5里面北扬克郡是哪里？我感觉是阿拉斯加或者加拿大某些地方。。。

WIKI原文：North Yankton is a fictional state featured in Grand Theft Auto V and is seen in the missions "Prologue" and "Bury the Hatchet." The state is located in the Midwest and may be based upon the state of North Dakota. Very little is known about the state, however, the small town of Ludendorff is located in the state, a city based on Fargo, North Dakota andBismarck, North Dakota. It is snowing in North Yankton during both of its appearances. The state itself may be named afterYankton, South Dakota.
