The article doesn't say it, but she got the idea from coach's pig manure mountain.
She calls her big mound of crap and dirt the Rob McGrath Pit.

Actually, I don't think Big Mo'll live long enough to acquire the bulk of the William Rivers Pitt, the
Jungfrau-looking 740-cubic-yard mound of antique swine excrement dating from 1875-1950, that graces this property, on which "volunteer" "heirloom" tomatoes and catnip lavishly grow.
In those days, the pigs were fed surplus from the gardens here, and most years were good years for tomatoes; the family always got much more than what they needed.
The pigs dined on lots of tomatoes, whose seeds passed their their intestinal systems undigested.
<<<knowing the source of these tomatoes, buys tomatoes at the grocery store instead; it's cleaner and safer.
But anyway, after decades, the stuff looks just like plain ordinary dirt.
