William Simpson uses geometry to distinguish the differences between a horse’s hoof and a cow’s and uses mathematical reasoning to measure the impact on grassland’s both private and public. If we don't keep the plant covered, that's there. We get catastrophic erosion and all that silt goes in the streams, covers all the fish, kills the fish, runs. Indians blame us and they're really not even pointing their finger at the right problem. The problem was the erosion where you get these big catastrophic fires, you lose all the ground cover, big rain comes all the mud. And so it goes and covers all the fish and it fills all the space in the ground. They call those arrests, then fish to do spawn. On top of that, they just roll away. They don't go down to the gravel. So you get sailfish, right. It's all connected. So if we manage it with a more holistic view, but that's how we used to ranch. We stretched with a broader vision about what we needed to do to have cost effective beef for the market. And a lot of times we had to be innovative. The government's not being innovated with our tax dollars right now. As bad as everything is covered in the economy and we don't start changing the way we're doing business right now, we're all going to be broke. And ranching isn't getting any easier either. I'd like to give all this land back to the ranchers, get all this land. It's only suited for grazing. It's flat. You can get out there and reseed it. Great areas. But we're trying to commingle wildlife and livestock and you just can't do that. Just Bill's vision, but fascinating.
