Fishing, as fun as it is, doesn't always provide the variety you might need. You may want, to put it simply, hunt.
Pigs provide the answer.
Some states, like Alabama, just require a small-game license to target them; others, like Georgia, ask for regular hunting paperwork. In Oklahoma, no license is required to hunt wild pigs on private land.
Often, too, there are no closed seasons on these feral swine; even night hunting and other opportunities.
Always check your state's regulations though, as they vary. Have fun but stay legal.
