He leased the land knowing what was going to be done with it… If he didn’t know, he’s either an idiot for not asking, an idiot for not thinking when he saw the opportunity for a cash grab, or an idiot for not reading the lease after it was drawn up.
Either way… Still an idiot. This is entirely on him.
Also, dude’s got cattle on 1200 acres(almost 2 miles of land) and looking for more… That’s the size of my town and the next town over combined. Not even the slightest bit of sympathy.
