I haven't been to one and don't expect to be invited to one anytime soon. I'd probably enjoy watching the animals they've grown there. Don't think I would care to hunt there.

They are legal. They should continue to be legal. If someone wants to hunt semi-wild livestock deer (depending on the size of the property), that's not much different from hunting free-ranging deer that have been manipulated to grow bigger antlers and bodies with intensive/expensive management practices IMO.

As long as they do no harm to our natural resources, it's really none of our business what they do behind their fences or on their huge exclusive but unfenced properties.

It's those who want our government to restrict the hunting rights and property rights of others who need to be watched very closely.
