They listed their "gas" budget for the trip at $2000.. I'll bet for 2 people hunting 6 different states the hunting licenses and tags was more than the $2K. Remember they are "out of state" hunters in at least 5, if not all 6, of those states.
I'm not knocking what they did as I would love to do it. I just wish they had been more open with the total cost involved of such a journey. I'd bet all included it was $10K, or more. BUT, that's $10K well spent and I would do the same.
A hog is nothing more than a bullet receptacle.
