The most succesful way I have found is to start knocking on doors. I have nailed 2 of my private spots that way. First I intruduce myself, where Im from, if there is anyone hunting the land. Be prepared with a permission slip for insurance purposes. Tell them that its so if you get hurt on the property your huinting at your own risk. If the answer is no be sure to thank them for they're time and leave them your name and number incase they change their mind. Just be respectable and offer to help with any odd jobs around the land. Also offer to be the caretaker of the land. The worst they can say is no. A slim price to pay for a potentiol hot spot. Thats the way alot of my bud's get their pieces also. As soon as the season is over I will be looking for a place in zone 25 to muzzleload hunt next year. I have 2 places now in 25 but its bow only which isnt a bad thing beings there is no gun pressure what so ever. Still seeing deer like its the first day of the season. Good luck in whatever you decide to do if you decide to go knocking on doors be polite and you'll be happy with the outcome. Im located in south jersey if your looking for land around here I can head you in the right direction.
