RE: Getting permission to hunt
I would not wear any camo... dress respectfully... and be clean shaven. Also, I would suggest leaving name, phone number, license plate number, and your email address. That way...you can tell them to email you the night before if they do not want you hunting on a specific day for some reason or another (like grand kids coming over and playing in the woods).
Also, in NJ they have a little form for the landowners to fill out for you... just in case.
Some farmers also need a helping hand sometimes.
