You can set a dead porky out on a plank or flat rock; come back about a week later and grab the big quills and sell 'em. Maggots will eat the rest.
Didn't the women of many American Indian tribes use the quills for decorating clothing, bags, etc.??
Maybe they might still be in the market for some. You boys seeing all those porcupines could make some pocket money.
