Yeah, although Wyoming land is reportedly good for some things (eg grazing), quick Google searches seem to suggest price per acre more around $450 an acre statewide (http://trib.com/business/land-values-skyrocket-in-parts-of-w...).

The thing is, agriculture fertility is not the only factor in rural land price these days -- I've heard ala the linked article that investing in land for hedging / portfolio diversity purposes is popular. It's also no surprise to hear that more aesthetically attractive rural areas will fetch a premium (I would seriously doubt the area around the Grand Tetons region is just $450 an acre for instance; the linked article suggests as much).

Wyoming's a great place to start a wind farm.
