I don't need someone to tell me the laws, for one thing I don't break the law not intentionally nor through ignorance. You quoted me so to me you were speaking to me. I have made the appropriate phone calls and yes it is the Markerville Natural area but as far a everyone is concerned the launch is gov't land and it is for public use. No one is going to write you a ticket for using this boat launch.
I have been putting up with people ripping up the places I have been fishing all my life, with their quads, to the point where I can't even enjoy going out there any more. So I don't feel too bad backing up my truck 20 feet to a mud hole, to pick up my boat.
This doesn't need to be discussed any further.
