You are fairly close to the Black Hills of South Dakota. I grew up in North Dakota and the Black Hills were a shock to me. They are a real deal mountain range right in the Midwest! Head to Spearfish or Rapid City and check out a local shop. I really enjoyed Crow Peak but I am sure there are many more. You would cross the Badlands on the way there which are also well worth a stop, or more.
