Nebraskans seem to take their college football very seriously too! I seem to recall that many Omahans (sp?) will travel to Lincoln for the games. Heck I know more than a few Corn Husker Alums in the Chicago area that make the trek for a game or two each year.
Until I moved to Florida, I made it to one a year. Drove from Billings, MT straight through to make it in time for a Saturday game. My blood runs Husker Red.
Everyone has mentioned some rally good stuff. The GA scene seems to be quite active there, too. There was always a fly-in somewhere close by, pancake breakfast, active EAA chapters, etc. Hangar space is generally pretty reasonable and available which will be important if you get your own plane soon.
I was looking at property out there about a year ago when I was considering moving back 'home'. There are lots of acreages outside the Omaha area - I was looking mostly north trying to stay within an hour of the airport - that were very reasonable. $200K would get you a nice home with a big piece of land.
There's also a lot of boating and camping at the many lakes and along the rivers. I'm hoping to go float the Platte in June when I get home to visit my brother. Oh, and all the small towns have a festival of some sort, sweet corn festivals for example, and of course the rocky mountain oyster festivals. Street dances and live local bands are happening somewhere every weekend in the summer.
There's lots to do, and as it was said before, it's what you make of it.
