Wow, that is an insult.
My area of Kentucky is far more productive than 99 percent of the worlds surface.
Go to Kansas, Colorado, Alberta, Montana and report back to me on how verdant it is out there and then start to knock Kentucky.
Go to Texas, Arizona, New Mexico, Nevada et.al. and tell us how great it is when it comes to raising cattle. The reason you could raise cattle in Texas and the Southwest is because of it vast expanses. They were vast but anything but verdant.
Geeze! where in hell in Arizona can you raise a cow per acre, don't look for an area were you can raise 10 per acre, because it does not exit out west.
