I do not condone breaking the law. But I talked to the local Game Warden about this. It went something like this:
Me: Hey Jim, What are the laws about transporting live hogs?
GW: Laws?

I didnt know there were any? Its not a TPWD law.
Me: I think it is regulated by the TAHC.
GW: Ha ha....like they are going to do anything. If that is a law I cant do anything about it and I doubt TAHC has anyone either.
That was suppose to be humorous....... but seriously was the general conversation.
