Interesting replies. I suppose I can understand the the fear of it becoming an open sale of access rights. I don't doubt that this already happens, however, that isn't what I was refering to.
Alot of people are very successful getting hunting rights with a 1.75l bottle of good whiskey or a case of beer. Others, with a bag of jerky and the time spent stopping for a hour to have coffee.
The biggest thing is to be respectful and try to understand the concerns of the farmer. Those concerns are usually of people shooting cows, leaving gates open, tearing up fields or planted winter crops. As well, the liability thing is a growing concern.
A bit of time spent out working would go a long way to helping with these concerns. As well, you would become a person that they would have respect for because they have got to know you and worked with you.
Not just some nameless hunter asking for access 5 minutes after seeing a trophy buck and wants to know right now and then go chasing after the trophy that is heading across your winter wheat where you don't want anybody going.
Basic knowledge of the layout of land and borders of it would be a side benefit. Knowing which field were planted into oats or alfalfa can make a big difference in how you hunt a tract of land. Knowing the borders would keep you legal and off neighboring land that you haven't got access to.
Anyway, this has been a informative for me.
Thanks, JT.
