What costs more raising a pig or shooting one in the wild? If the answer is the latter perhaps someone can make a fun business out of it :)
Feral hog meat, unlike typical pork, is a deep red and can have a wild-game taste. It makes for great sausage and barbecuing but you wouldn't necessarily want a ham sandwich everyday in your lunch.
Many outfitters charge both the hunter for the opportunity to hunt and the farmer for the removal service.
