True story about his son.
He lives fairly close to where I live, and one of my friend's wife's family are also pretty big farmers. I guess Buffett has just been buying up every single bit of land that comes up for sale in the central Illinois area around him, so her grandfather finally decided to prove a point that someone else could buy land.
He ended up outbidding Buffett, and paid something like $19k/acre, I think for around 40 acres. Now it is something he could only do once, but he did what he said he'd do.
