By you getting the property for fishing and not hunting,I would say thats a great step. Sharing your harvest of trout is the next step.Hey,it may not lead to a hunting spot but it is the right thing to do. I share the kills off the land I hunt with the owner.It took me a couple of years to get permission from him,but it has been worth it.Grouse,turkey,deer wabbits.
His brother, who has the property beside him will not let me hunt on it,he will let no one. It aint him really it,s his mrs,s. Man does he have prime big buck property. Oh wait those are his cows
Be patient,I would think a year or two and you may have yourself a new friend and a place to hunt turkeys.
