The original post just asked about hunting pigs- no mention of feral, or wild, or anything. You don't find javalinas very far North, and certainly not north of the border states here in the USA.
You don't have to go all the way down to South Texas to shoot feral hogs. They are all over Texas, and also over many other states. They are considered nuisances in most jurisdictions. In Florida, you can kill one a day.
As for meat fit to eat, you obviously don't know how to prepare meat properly, or you would never make such an assertion. Strong flavored meats can be made edible by soaking them in salt water, or in water with vinegar, to draw out the blood, which carries most of the enzymes, that make the meat " strong " smelling.
All wild animals, including feral hogs that are not feeding on Corn, are going to taste strong. Deer that feed on pine bark and pine nuts have a bitter taste to the meat, compared to deer that feed on corn and soybeans, which smell and taste like beef.
Most people don't like bloody meat, and dislike Liver because of it. If you draw out the blood so that the meat goes from dark purple/red to pink, the flavor improves dramatically. You do have to trim away all the fat and sinew, as those tissues also carry enzymes that consume sugars in the muscle, and turn the meat both bitter, and tough.
Liver, eaten fresh is as sweet, and tender as Prime Rib. Honest. But liver that is allowed to age continues to break down sugar in the organ, making it tough and bitter- just like the liver we were served in our school cafeterias when we were small school kids. YOu can improve the cooked taste of wild meat, including boar, or feral hogs, by using a sweet BBQ sauce for basting, by using sweet onions, and bacon from a domestic hog to sweeten the meat. I also like to use green bell peppers, and a Granny Smith apple( tart Green apple sold for making pies) cut up in sections to garnish the meat, baking roasts in aluminum foil, to help sweeten the end result. With proper soaking, all the smell and bad taste are gone, and its up to you to then spice up the meat to your own preferred taste.
