congratulations on the acquisition. No better feeling than picking up permission for a new parcel of land. Except for maybe that first bird you kill there.
Shellwaster, if I were you I would go pay a visit to some of those landowners you called earlier. I get permission a lot higher % of the time in person than over the phone, I think it makes a landowner more comfortable seeing your face and being able to get a better first impression. Especially since you already called, that is a perfect set-up that has gotten me into properties. They say no over the phone, and then let me in after an in-person visit. "Hows it going, I'm ______, I called about turkey hunting permission awhile ago? Just figured I would stop in and introduce myself in person...."
Shoot the bull with them for awhile, talk farming, hunting, whatever, and you will be surprised how often they have a change of heart and let you in after seeing you are a responsible, respectful guy.
