We can't tell you anything about where you live. You have to decide where you are going to detect based on common sense, gut feelings - and the law. I have detected in many places not open to the general public after talking with - and making a personal relationships with those in charge. If you go to "City Hall" and ask permission to hunt a city park, I can almost guarantee you will be rebuffed. Yet if you just go to the park at 6am, and leave by 8am when the dog walkers come out, nine times out of ten, nobody bothers you. If you are respectful, know how to use a hand digger and don’t leave any signs you were ever there, MOST often you won’t be bothered – in my personal experience, which has no bearing on your reality. Do NOT take anyone’s advice here on the forum – including mine! Use your head, make up your own mind.
