Welcome to the site! Nice hunting choice for sure. I have one park that I hunt that has been hit hard for many years by countless people. Good finds are very few and far between. But one day I decided to try the grassy islands in a large parking lot. Lo and behold, it must have been virgin ground. Pulled out tons of old coins and artifacts over several months. Guess nobody thought far enough outside the box. But parking lots have tons of traffic from the time they are put in, leaving lots for others to later find.
