If the property isn't posted otherwise, that's exactly what it means. If I want to take a hike out on government property, picnic in a park, or swim at the beach, I'm not going to ask permission from ANYONE. It could be next door to a private residence or out in the boonies, doesn't matter. If it's not private property, or for some reason off-limits, it's fair game. I've had people who didn't think I should detect in a park or beach too. So what? They have their head up their backside. It's not going to stop me from pursuing my happiness by detecting legally. Respect is a two way street. I'll do it legally and not leave a mess, they'll need to know the law and not get upset by something that is no big deal. If you're squeamish about doing parking strips/parkways, fine, don't do them. Keep in mind that those same people who would object, would probably object to you hunting a park too. Are willing to give that up because of their personal feelings? You might as well give up the hobby if you'll only hunt where everyone will love you.
