Asked Bruce, the pumper guy, where he unloads the truck. Said they used to sell it to farmers, but now it goes to a processing plant. Fine is 10k for dumping it into a field....
I can say for certain my grandpa and my dad didn't pay anyone to spread poo on our fields! Those two are tighter than boogers in Washington's nose on a quarter.
But to be honest, around here at the time it was either a field or the Ohio River.
