Nebraska splits it up and you get more properties that way. Lots of landowners simply don't want people rifle hunting deer and that is an easy way to do it.
However I've never heard of wildlife viewing property! Hope they don't spend money on that. Those people aren't buying licenses to support the lease!
Some of the best wildlife viewing areas are around the Refuges like Salt Plains.
Some of the best deer, duck and goose hunting is in that same area. I don't see them getting any $5 an acre viewing lease. (just speculating, don't really know what the price is for that land.
