We were down there a few years back and tried to hook up a DIY hunt. Couldn't get a straight answer of whether we just needed a Nonresident license, or an Exotics. While there, we looked through the classifieds for processors and saw more than 1 article that said (paraphrasing) "If out of state, make sure you supply either a WCO in person, or an Exotics license."
Decided right there, they were more interested in making money than dealing with a hog problem. Offered help, they deciined, their problem. Good luck with it.
