It sounds like your dad needed to sell the land. Maybe because he was worried where he was going to "live" come september. You don't say in your post.
When my mom and dad decided to sell "their" 130 acres in PA years ago, I didn't expect anything from it. I lost some prime hunting land also. They worked it, they worked for it, they paid for it. It was theirs, not mine. I never got anything when mom and dad passed away either.....didn't expect it, they had given me enough.
I hope you find a new place to hunt and hope everything works out for your family
