We are sure happy to have you visit Minnesota. My husband and I do not live close to Bemidji, but we have visited that area. We live near Pipestone, MM - home to the Pipestone National Monument - which is a wonderful place to visit. You can look that up on the internet when the government pages are up and running. Our area, as with many different places in Minnesota, is full of Indian History. It will be easy for you to do research and very interesting. Pipestone had an Indian Boarding school 1892-1953. Our Museum and Historical Society have much information and pictures on the subject, as would the Bemidji Historical Society, I am sure. I work at the Minnesota West Community and Technical College which sits on the site of the old Indian School. Happy traveling!
(Although I do not use Wiki for most information, this may tell you a bit about the Leech Lake Indian Reservation near Buchus.)
