North Dakota South Dakota or Both?

So thinking of going on a long tour.... Woundering if either North Dakota or South Dakota would be a nice place with nice people? Or if I should stop in both places? I will be bringing my sexy exotic girlfriend with me. I am also exotic as well.Looking forward for a trip that way soon really soon.

Come to Fargo thats in North Dakota. you wont regret it :-)

Sioux Falls in South Dakota ... Will be more memerable than Fargo.

Rapid City, South Dakota
