We are very fortunate in our latest move - next door to my daughter & son-in-law. We'll be able to take off fairly spontaneously because they'll be able to handle the chores. They'll also be able to get away a litle more because we'll be there to take the kids and dogs. We've taken down the fence between their 2.5 acres and our 5 acres, so we have a combined 7.5 to play with. Our house will be far enough apart so we'll each have our privacy, but the barn will be in between so we can all use it. I can use my s-i-l's garden tractors for finish mowing, and he loves my TC18 as much as I do.
As far as never leaving the property, my wife has already said she anticipates selling our NC mountain cabin where we have been going for "isolation" for the past 15 years, because everything we need will be at the new place. I didn't think anything would ever persuade he to part with that place! But, we still do have the old Pace Arrow so we can get away - in fact, it's in for a little rejuvenation as I write. When we bought it 7 years ago (1988 model, 8 years old when we got it) I promised her 10 years before I bugged her for another one - but I'm starting to look now for a diesel pusher, since we both turn 63 this year, and have a little more time for this kind of foolishness.
We probably never will give up work entirely - I'm taking a year off to build the house and barn, etc., but will go back into the business of fabricating custom outdoor kitchens on a part time basis - it's just too lucrative to give up entirely, and I enjoy it. She'll likely never stop seeing patients as a home health physical therapist, at least part time, she loves it so much.
So, there's the Horner recipe for rural living...some work at things we like, a little play in the outside world, and a lot of play at the country place, leavened by our family closer than ever, and spiced with our granddaughters next door. If my son ever decides to get married (he's 32 and still thinking about quitting work to sail the Caribbean), there's more acres on the other side of my daughter's - he's thinking of buying it "just in case".
God, life is good.
