i have asked people for permission that have told everyone else NO. they have even told me this many times. first thing is, dont call them on the phone. go over to their house and ask them personally. they are more prone to say yes when you ask them face to face. this is what i do: i walk up to the person's house and knock on the door. [ i wear a decent pair of clothes, nothing fancy but some everyday clothes that i would wear to school that are nice and presentable. not clothes i just got done mowing the lawn in] when the guy answers, address him by his last name [ex: hello Mr. Johnson] my name is_______. after that i shake his hand. try to use good manors, have good posture, and make good eye contact. i tell him where i live and that i am looking for a place to bow hunt. i also tell them that i am repsectful of other people's property and that i am willing to do whatever it takes to be allowed to hunt. tell him you will do any work that he needs to be done around the house.

hope this helps you

oh and i know that this probably sounds stupid and sounds dumb but now i have 3 additional farms to hunt since i started bow hunting last year.
