I previously noticed that Goldie, in "Ducky Mt. High" somehow knew (as if she's got x-ray vision) that the gold was originally on Mr. McD's land, even if the gold trees were originally on hers.
Is it possible those kind of pine trees have roots that ALWAYS grow sideways, in a particular direction and for a particular lenth?
And Goldie, being a lumberjill, knew that? And thus DEDUCED where the gold was?
