I find it helpful if I bring my son with me. Usually, I explain that I'm looking for a place to hunt with my son. He is 12. I tell him to stand up straight, look him in the eyes, and shake hands. I tell them I will park on the road and walk in. Most of the people I talk to are worried about vehicles damaging their property. Also, I recommend doing some research on the adjacent properties before hand. It always helps to be able to mention something like 'I know the Smith property starts at that tree line'. Usually, I will look at the property lines from the County website and then compare to Google Maps/Satellite/Earth to get a lay of the land.
