Good luck...
Corn is $23 a hundredweight... mediocre hay is $110 a ton. Water is.. Well, where you find it. That's NW Wyoming (Park, Big Horn, Washakie Counties). Unless it's irrigated, it takes about 50 acres to support one horse. Raise something that eats grasshoppers.... like Chickens, Turkeys or Guinea Fowl.
As the old joke goes... The land is so poor, You have to sit on a sack of fertilizer to raise an umbrella.
