Welcome aboard Huntfan. I guess your new to detecting, if so the best place to start is in your own yard get to know your machine real well and learn how to dig a target without damaging or scratching it. When you branch out try the local soccor fields Debs park and the municipal. The train right of ways like up along Randolph sometimes dole out weird stuff thou not usually valueable. Neighbors or relatives yards are good to if you have them in your area . As stated and as you know it can be a tough area but the stuff you find is were you find it and if someone could tell you where it is then they would have gotten it for themselves already. Watch were local workers may sit on a lawn and eat lunch, good place to search for pocket spills. Lawns adjacent to fast food joints were the school kids hang out may produce. Any time you see concrete or asphalt being removed try to search that area as it hasn't been checked since before the hardscape was poured. Ask the older folks that have been around where they hung at you may learn about long forgotten places. Good luck, Buena Suerta, Urb
