I'm guessing you didn't grow up on a farm.

There will always be some farmland effectively for sale; but there will also be other farmland which will never be for sale, no matter what the cost. The latter are generally "homeplaces", which have been in the family for generations. Heritage, blood, sweat, and years of hard work bind you to the soil, the land. It's more than an emotional attachment--it's almost spiritual, almost core identity.

It's an essential part of you and who you are.
