Thank you for your kindness in mentioning this very good book.  My half sister knows Professor Fenn at U.  of Colorado.  My half sister goes to sister school Colorado State University about 40 miles to the north.  I think the book is objective and fair.  I also think it supports much that I have said about what indigenous means and what we contributed to the Great Plains, to the USA,  and to the world. We shall endure!
