In addition to the above, I would also bring a CV with you. This will help to let them get to know who you are. Tell them you will let them know when you are going to be out there to - tell them you will call ahead if they like. And offer to give them some of the kill. I plan on asking a nearby landowner soon, and offering him half of the meat.
Remember to consider this an interview, just as if you were applying for a job you want, and act and dress accordingly.
Good luck finding your honey hole!
