Hi
O.K. - so this is like the post I've been waiting for apparently as this is (currently but not forever) my neck of the woods. First off, is there any particular reason why you want to drive to Sioux Falls for the night? I live just north of FSD and have spent a little time in OMA and feel like, honestly, there are better restaurants, etc. in OMA. If you have your heart set on coming up this way - send me a PM and I can suggest restaurants, etc. in FSD. It's really not that bad - no traffic, friendly people, decent enough food, good coffee, good beer and all for under what you'd pay for a single mineral water in NYC.
Oh, and airports...to fly out of it all when you need to.
