RE: Restricting access to property that he doesn't own.
TSOC, I am just gonna play devil's advocate here. It is hard to tell from the post. Is the road on his land and just happens to access the property you hunt? I know of a couple of cases near my father's house where an access road was on the property and used by a number of people, but no one had actual legal rights to the road or written permission to use the road. It was just "assumed" that it was alright to use the road. Then, when the property changed hands, things changed. Is it possible this is the case?
