I dont know anyplace specifically BUT I do recall detecting at a long closed drive in movie theater there right south of rt50 and the expressway. Ask around someone will surely know the place.
Its trashy and hard digging but the items were shallow due to the hard packed ground. After you survive all the pull tabs, pop tops, condom wrappers etc etc you will be conditioned and GLAD to detect anywhere else.
There was silver coins and jewelry last time I was there about 10 yrs ago.
Best of luck
