All great advise, another reason to be polite is one property owner may know another. Also go start asking and making relations now don't wait because everyone else is going to wait to and that same owner may start getting so many people asking it will put a bad taste in his mouth for the late guys. Never go knock on the door to ask in camo and don't go at bad times of day ( dinner etc. ) Keep relations with them all year don't just use them for a few weeks in the Fall. Stop in now and then throughout the year, if you harvest something bring some to them, bring them fish in the winter etc.
