That's what I said too, but I guess her parents worked for the military or some shit so she was in NB for a while.
And I forgot to mention, Deadwood is an older HBO show that ran for three seasons. It came on after The Sopranos. It takes place some time after the American Civil War (I think), in a place in South Dakota that's in an area that isn't actually part of the American government because the Indians still own the land, or something kind of in between. So it's a lawless Western TV show starring Ian McShane and Timothy Olyphant. It seems to be at least inspired by real events and people. Wild Bill Hickok is in it.
