I agree with flyguy, Sw SD is loaded with mule deer and the grasslands, while huge have great spots to hunt. I will be bow hunting for the 1st time this year and am definitely going to get tags for the Black Hills and the grasslands. Custer or Hot Springs would be the best places to stay for this area. I am in Custer so I know the area. Let me know when you are going to be here, maybe I could help you to pick the best areas to hunt.
Also, where in WI have you been hunting? I am from there originally(moved to Custer 6 1/2 years ago).
