Eastern Kansas
Are there particular towns you are thinking of?
Tonganoxie?
Great schools (even though your kids are grown, you need a great school system to get lots of other perks of an enjoyable lifestyle and comfortable resale, should you decide to) affordable housing of all kinds: single, condos, apartments, own or rent long term.
Small, friendly police departments who know your name and look out for you and your home, should you be traveling.
Door-to-door mail delivery (If in an older single family development) comfortable building codes and restrictions. Kids to mow lawns, shovel snow and water your flowers when you travel.
Taxes not too high and voters who balk at raising them when pols think they need raising.
An airport 30+ minutes away and easy in and out, with 2.5 flights to anywhere warm when you tire of too many cold, snowy days.
Right now, were about halfway through winter with less than 5 total snow!
Come visit sometime, youll find were very friendly and you just might want to stay awhile!
Eastern Kansas...
I was going to suggest the Flint Hills of Oklahoma. Very close in area, but I’m not familiar with living in eastern Kansas.
