I looked out the window of the plane when I saw that we were finally going over Sao Paulo and this is what I saw... I said "Oh my God, Gostavo, what is all of that??" He said, "Oh it's just the farmland. You don't have in America?" JUST FARMLAND??? We have farmland in America for sure, but not farmland that looks as if it could be hung in the contemporary wing of Museum of Fine Arts!
