There are enough docs actually but they are paid very well here and cost of living isn't too bad. Lots of tall, hot Norwegians (see avatar). The Sioux are occasionally attractive but not usually. Cherokees are better and aren't in SD for the most part. It is actually surprising how rarely whites and native americans date each other here. Other than that there just aren't many other races around. There actually aren't even that many native americans outside the reservations. If you want variety, you won't find it in South Dakota. My HS had 800 people in it: about 20 native americans (about 5 were FAS), about 5 asians, 1 guy who was 1/2 black and the rest white. I met my first black woman when I was 24; not saw, but met.
Not sure why I went into such great detail about the racial mix of South Dakota but I did.
