I want to add that even warrantless entries due to medical emergencies, domestic violence, etc. are good for prosecution. They still would need to get a warrant after finding the stash but that's a technicality, you still get busted nonetheless. In fact, legally, basically anything outside the "curtilage" of your home (the immediate vicinity) is fair game. This includes wooden shacks, greenhouses, bags of trash out in the open. If your house was on, say, an acre of land and the perimeter had trees blocking view from the street, the trees don't matter, the police can still waltz onto your property right up to the curtilage. (The moral of the story, buy picket fences, they can count towards being the curtilage.)
