I have also been in a similar situation. My Dad his Dad and a couple friends have been hunting this property owned by a farmer for over 30 years. We use to bring him wine, meat,and clothes for his kids. We were pretty much the only ones that hunted there with the exception of a few locals.We'll the farmer lost everything(didn't pay taxes or something) So this big dairy farmer bought it out, so we immediately obtained written permission from him. Now there are like 10 other guys who hunt the land w/o permission because this big farmer lives far away. Granted it is a big area, but thats not the point.
