RE: Pardon me while I pat myself on the back.....
If done so, professionally and courteously (seeking said permission)......I think we could ALL hunt more grounds than we do.
I always hand-write landowners a letter after my initial meeting with them.....whether I'm turned down or granted permission. My two best spots are those in which I was denied permission, initially......but later had them contact ME after receiving my letter to rescind their ban.
I thank God for these opportunities. I don't know where I'd be (hunting-wise0 without them.
