I have had excellent response from landowners when I approached them regarding permission to hunt on their land.
A few polite refusals, but they are definitely in the minority.
I remember once, years ago, while driving very early in the AM to a crown land parcel, I spotted a very respectable muley buck laying in a farmer's field, chewing his cud.
I knew the farmhouse was about ½ mile away, so I buzzed over there and was relieved to see the lights on.
I knocked on the door, and spoke to the landowner, who was very nice, but said he would rather not have someone armed with a high powdered rifle shoot that buck.
He added that if I was armed with a muzzleloader or was an archery hunter, he would allow it.
I told him I understood how he felt, and gave him my details, just in case he changed his mind. I left, with the promise I would not try to circumvent his wishes.
Lo and behold, about a month later, close to the end of the season, I got a phone call from the farmer. He said if I still wanted to shoot that nice muley, to have at it.
Only condition was I had to let him know when I planned to come to hunt.
He declined the offer of a big roast from that muley, but was willing to accept the Crown Royal I offered him.
Hunted his property quite a bit over the next few years till I moved away. Pays to be tactful and polite.
Regards, Dave.
