"For three decades, Andy Henry has declined $20-30 million offers for his 21-acre, 175-year-old farm..."
OK, I'm gonna play the realist here.
Let's compromise with the above numbers and say Mr. Henry could get $25 million for his property.
He could take that cash and buy a much bigger (than 21 acre) farm in Central or North-Central Pennsylvania, which would probably come with a homestead that looks pretty much like the one in the picture above (which looks like what I'd call a "Pennsylvania Gothic" style).
He might even have the old house dismantled piece-by-piece and rebuilt at his new spread.
He'd end up with a couple hundred acres, an infrastructure ready-to-go, and get on with life.
Sometimes it's better to just "take the money and run..."
