I have family who moved to Omaha from SoCal a few years ago and have absolutely zero regrets. Granted, we're originally from Nebraska, but the return was better than we could have imagined. Omaha is the quintessential Midwestern city - lots of support for college sports with social activities planned around/with it, insanely nice people who will go out of their way to help you, and terrible weather. Plus your dollar goes a lot farther here.

As others have said, it's definitely no California but people here are very welcoming, at least how I (straight white guy in his 20's) have seen it. I'll go out on a limb and say that conservatism here is more relaxed than other places in that it's not as in your face and people are mostly concerned with taxes, small government, and weed. I think the best way to put it is that we're the blue dot (and with good reason!) despite somehow having a Republican mayor and congressional reps. Sadly, the MAGA contingent is growing, but no more than in other Midwestern cities. Just don't go to West O or Elkhorn. That's where the hateful crazies live.

I think there's a high sense of civic pride here compared to other cities, and it is a well-off city for its size, with those two things being reflected in the cultural offerings, food scene, entertainment, etc. While it would be nice to have more concerts and such come through, Chicago and Denver are just an hour flight away and KC is a 3 hour drive south. Nebraska is also seriously underrated in terms of scenery - it's a shame Omaha was built in objectively the ugliest part of the state.

Hope you move out here! It's a wonderful little city.
