My wife is from Kansas and lived in KC for quite awhile.
You have a baseball team (Royals), a football team (Chiefs), a racetrack (NASCAR). She said if you want good ribs/BBQ according to her the place to go to is Arthur Bryant's Ribs -
http://www.arthurbryantsbbq.com/ - kind of the hood but you probably won't get mugged.
If you like hunting they have some big ass deer and bird hunting. Kansas has what's called CRP land, which is private land that's let go to nature for the critters and you can go hunting on it (her brother is about an hour outside of Wichita and I've seen the bucks and bird hunted).
As far as where to live and not to live, good school districts my wife says the Kansas side is better and said the
Shawnee Mission School District is a good one.
If you're in Kansas, once you're a resident, you can actually walk into a Walmart, buy a gun and walk out with it one second after it's paid for.
College football is huge.
As far as off-roading is concerned I've been around Wichita, Hutchinson, Russel, Lyons and that general area and there ain't much. Every section of land has dirt roads all the way around it but they're mainly flat (San Francisco has steeper hills and more of a reason to use low range). You might get some mud or snow action but that's about it.
The wife mentioned shopping in KC but if you're like me it's of no interest. If you're married perhaps the Mrs. will like it.
You are closer to Colorado, I know they have plenty of stuff to do. It's not a bad drive from KC to Denver.
Hope this helps.
