The Sacred Buffalo Vision by Robert J. Juneau and Robert C. Juneau pg.157-158

You can never grasp the magnitude unless it is seen with your own eyes. That is why we came here to see what it would take to do it. I would like to give you a comparison. We have a ranch in Texas which in size is about the same as this reservation, about a million acres. What can be done with the proper financial setup on this reservation in comparison with a tract of land of similar size? The King Ranch is the largest ranch in Texas, privately owned by a family in South Texas. Probably the only resources that ranch can lay claim to is in the form of ranching and oil and gas. In the beginning it had nothing but its ranching and from that developed a multi-million dollar corporation. Ten or twenty million dollars would be nothing compared to its total value speaking only of its ranching. It has only been fairly recently that the oil companies went in there and took over the development of their oil and gas.
