Make no mistake, the loss of hunting ground is not due to greed. It's due to too many people. As our population continues to grow, we will continue to loose hunting ground. The fact that a private landowner allowed public access was a gift. To believe the next owner "owes" it to the public to allow public hunting or denying his right to sell to whoever he wants is rediculous.
I recall a similar situation in downtown L.A. where a landowner had a large lot that he allowed locals to farm a vegetable garden. When he decided to sell it, they protested publicly (picketed) and badmouthed the landowner, then sought an injunction and further legal action. These people were given a gift for years and they thanked the landowner by calling him names and threatening to sue. Go figure?
