Harry,
Like I said..you are a victum of your own success !!!!:D

First, I have to see if I can get a farm to hunt on.
The farm I hunted for years I was introduced to by a hunting buddy. When he passed away I was already established with the farm owner.
The farmer was crippled up from a life time of carrying milk pails and couldn't get around well on foot. He was glad to have someone walking the 300 acres which was half hay fields, half woods and ALL HILLY, putting up and maintaining the posted signs and keeping the woodchucks from trashing his hay fields.
I also watched for signs of others trespassing, or dumping, and would report it to the farmer who liked riding out in his truck and taking pot-shots over the heads of trespassers with 20 ga slugs. Even shot one guys truck radiator when he found the guy parked, hidding in the back of an upper field on his property. Another time he jammed a stick in the horn to kill the battery of an unknown car he found parked behind a hedge row in one of his fields .....turned out to be a car my hunting buddy forgot to tell him he'd just bought the night before.
And like Mark said, I'd pick up any windblown papers, trash, hay bale twine, or plastic, etc and pack it out. And I'd always offer him a share of any venison, which he'd always smile and politely decline.
Farms are alot of work. Ya gotta think about what the farmer needs before he'll even consider what you want.
Paul.
