I think once you live in Lincoln or Omaha for a bit you start to get bored of it too.Do those same kids say, "Wow, I'm living in Lincoln or Omaha! How exciting!!".
I think more of it comes to earning opportunity, where your friends and/or boyfriend/girlfriend are at.
I do see what you're saying though. A 20-something would see Lincoln & Omaha as more exciting than Broken Bow or Holdrege, but I do think much of that is swayed by what I mentioned earlier.
It just takes longer to get bored, probably.
