That was my thought as well.
Our house is 200 feet back from the road, with a narrow driveway off the road. Can't I expect a certain level of privacy? Or, do I get that from my ar's?
It all depends (though I'd trust the latter more than the courts

).
Seriously. There are three levels of 4A protection according to the Court.
The strongest is your home.
The second strongest is the "curtillege" (the area aroud your home like a FENCED) back yard. Its not as strongly protected as your home, but at least SOME expectation of privacy may apply (eg, the cops can look over the fence, but not enter, without a warrant).
Finally there are "open fields", land you own and may fence, but at some remove from your home. Here? You basically have almost, but not quite, zero expectation of privacy.
The question for you M58 is if they call that big yard curtillege or an open field. We all know the answer, but something as silly as a three foot high fence might make the difference between a search being upheld or thrown out. Me, I advocate a mean ass dog you aren't particularly attached to. Name him "Lawyer". Let the cops negotiate with him. If he gets shot? Well, you got your money's worth.
