As more and more post 70-75 yr old farmers retire/expire, often their offspring have established off-farm careers away from the farm. If the available acreage is under 3000 and they don't have equipment/knowledge to farm .. it's often sale time OR worst yet ...; place it with a farm management group like a bank. Permission to hunt is rarely granted by the mgt folks; they just don't want the liability or the problems associated with multiple requests. Some awful good goose-hunting fields in central Il have become mini refuges that make hunting in surrounding fields that much more difficult. My guess is in 50 yrs there will be few family farms - as we know them today - in the intense agri-belt of the midwest ... all gobbled up by super large corporate farm organizations. Hunting may become largely high fence and put-n-take.
