to my knowledge no there arnt any just roaming like the hogs. You can however, if lose and free ranging, drop one anytime as long as you have the proper licences and your a member of what ever club you shoot it on (ie. dont trespass). We had some falla get loose after hurricane Katrina and people were chompin a tth ebit to get them, needless to say they didnt make it 2days in the "wild".
