We are looking into leaving our acreage to a nature conservancy. It's something we've wanted to do to make sure our land doesn't end up with a bunch of houses on it.
About 25 years ago, one of the farm fields on our road was for sale, 60 acres. We didn't have the money to buy it. Who usually buys that much land? Farmers and developers. Fortunately, a farmer bought it. As much as I don't like him using herbicides/pesticides, at least he rotates his crops and plants about half of it in alfalfa for 2-3 seasons. It's hay for his cows, but it also helps the soil.
And he didn't put 20-30 houses out there. Hopefully he/his children don't do that before hubby and I shuffle off this mortal coil. We are never moving. As I've said, I'll leave here horizontally.
