The only way I've ever heard of hunting hogs other than still hunting, is with hounds. I know a few people that have done this and they say it is quite a rush, dogs barking and growling, hogs sqealing.Once the dogs get the hog at bay, then you go in after it. I don't know about any calls, but these days they seem to make a call for everything with fur or feathers. I guess soon there will even be some kind of fish call you can blow while your out on the lake.
