Ok, I'll say a few things since I'm from Kansas....
1) Being less than an hour from Salina, Hutchinson, and Wichita is pretty good. I'd sooner cut off a limb than live in Wichita, so out of town but not too far away isn't bad. Salina is growing at a pretty good clip.
2) $100,000 for a rural area buys a nice house, not a shack. The person making that comment must live on the coast where the prices are just insane. Here in KC, it's about $200,000 for a pretty nice home (by that, I mean a new build, nice size, good construction....don't like the quality of the $150,000 level which is where they start in the most expensive county of KC).
3) I've always lived in KS, and have never even SEEN a tornado. If tornados are a major fear for you, you need to get a life, because elevators, escalators, shark attacks, small dogs, and bugs must terrify you....
4) I wouldn't retire there...at that age, you want to be closer to hospital services.
