Offer to help out, from farming, mechanical work, or cleaning the gutters.. We hunt a farm and thatwas the first thing iI do offer to help leave my number so they can call, I have learned just as much by doing this, how to pull calves, run tractors, castrate pigs and cows, and much more..
Me and dad were coon hunting and went through a lot with calves in it crazy things ran in to the fence a broke it, dad was freaking out trying to get a hold of owner I just ran them into the barn lot and shut the gate. Next day the guy called dad wondering what he was talking about so dad explained, owner told dad it was about time he hunted with someone that had sense.. Well what we didn't know he was having problems with other hunters leaving gates open and mixing up cattle. If you want to piss off a farmer mix up there cattle. 2 weeks later locks were change and we were the only ones handed a key. We turkey hunt, deer, and now yotes..
Even if your not good at what they need help with the efforts counts, don't forget Christmas cards, summer sausage wine it all helps
