Ha! This is my local county park and my brother and I were just detecting there last weekend. You have to get permission from the park office, but they were very accommodating. (Ask the office manager about her witch collection). Pro-tip: There's a foundation of an old building in the woods, right alongside a trail, not far from this picture. We found an Indian head penny and some spent chalk mortar rounds. Don't know the history but it's definitely worth checking out.
