Now you do. If you haven't been banned. Don't worry bout it. Now lets see what we can can do for your hunting situation.
Make peace wiuth the guy and then work with him. Herlp the father son team out. But most of all get this guy to help you and your GF out. Its her folks land. Like I said. Make sure its OK with the landowner with you taking control....... I used to sell cars. Sell the in-laws the idea that you need a little control to get their daughter to take a deer. Once she dioes though the land will change.
Good luck. From your northern friend
PS...... sounds like you have a keeper. Don't puckit up.
