Hi Sylvan,
I am a New York state resident and that is where I was hunting at the time.If you are able to direct me to the law that specifies that an individual must have written permission of the land owner I would appreciate it.As a result of this experience I have an increased sensitivity to these type's of issues.
I wasn't aware that written permission was required.As I had mentioned in my post I came out of the woods and went directly to the Police Station where they indicated to me that if the land wasn't posted I couldn't be prevented from entering it.I wonder if the police department's interpretation of property laws are wrong? If asked by a landowner to leave a property I certainly would,I would ask though that they give me some sense of their property boundaries.I still think that properly posting is the thing to do.It removes all question as to whose land is whose and where the property lines are.

I don't know if I mentioned it previously or not,at the time I encountered this non land owning woman I was on a mountain road (four wheel drive type stuff)a number of landowners have a rightaway on this road,one of which I had permission to be on it from.I exited through a piece on non posted private property to avoid altercation.

I am far from perfect but I have no problem hunting on land that is not posted,provided it is in remote settings.I have had many instances where I have hoofed to a mountain top to run in to a string of posted signs,while I wasn't thrilled about not being able to go further I always respected the landowners rights.
I intend to become intimately familiar with all state owned and publicly accessibleproperty in our area as well as finding out as much as I can about the contiguos property owners of land that I have permission to hunt.
