I have tried to get access to a specific property for 6 staright years and was always denied. This year the landowner had a pest problem and none of his non hunting neighbors had a solution so I got a call asking for help. I took care of the problem and now have access to archery hunt that sweet piece of whitetail sanctuary heaven. I only hunt private land for deer and when I take a deer from that land I make sausage, jerky, smokey sticks, sweet bologna, etc, and I always give some to the landowner. I also clean up any trash I see on those lands leaving it better than it was before I was allowed to hunt it.
Dress respectable like you were going to church, taking a kid with and explain to the landowner you are trying to share and build an appreciation for wildlife in that child and you are looking for a safer place than public lands for the child to experience the outdoors and spend less time on video games. Most people who have children will understand that point. Not saying just use your kid to get what you want!!!
Also ask if the landowner is having problems with skunks, coons, rabbits,groundhogs, etc. in their garden and offer to relocate those animals with havahart traps if legal. Draw up an agreement for the landowner waiving your right to sue for any damages to your person or property and list your phone #, vehicle description and plate # if the conversation leads to getting permission. Leave a blank line for the landowners name in the agreement and both sign and date at the bottom. it's good to have a copy showing you have permission for yourself. I carry duplicate forms in my truck at all times for any time I get permission to hunt private property, it's better than having to go back and bother them a second time.
