I'm planning on setting one of my stories in a small(ish) town in a plains state in the US (possibly Oklahoma). I've never been, but wanted to know if there's anything I should be aware of to keep it authentic? Are there any research materials you would suggest (books, articles, websites, etc.)? Kathleen Norris' Dakota: A Spiritual Geography kind of inspired this and the setting fits perfectly with my story's plot. Thanks for any help and suggestions!
