"It’s been a long time since anybody was out here, gathering the wild forage. But now the grazing pressure is off the native plants. And there’s no more plowing, or crops, or herbicides, or fertilizers. So even though the weather’s bad, some of those native plants are coming back pretty strongly. Stuff like poppymallow, and devil’s claw, and prairie turnip. There’s nowhere near enough food for a cityful of civilized people. But for a little tribe of wandering nomads, who can cover a lot of ground, well, actually, there’s quite a lot of food out here, especially in spring and summer."
