I start by asking for small things. For example, I rarely ask to bowhunt deer right away. I start with permission to shed hunt or turkey hunt. Most farmers aren't big fans of turkeys, so they will gladly let you hunt. If you get on, make sure you buy them a gift in appreciation. Treat the land like it is your own. Then when you go back for permission the next year or for some other type of hunting, they will remember how well the first season went.
