The Omaha Zoo.
If I had to pick more:
* Cost of living + employment opportunities
* General niceness of most people
* Four seasons even if three get snow
* Easy airport access (in eastern Nebraska)
* Amazing natural spots of beauty that aren't packed when you find them
* Our unicameral + officially nonpartisan legislative system (even if it needs work + more Cavanaughs)
* Our split electoral votes
* Our cities punch above their population weight in amenities
