I am heading to Indiana towards the end of June, specifically Plainfield for a couple of days and petersburgh which is way down south in pike county.Anyone from around there know anything about the area or any likely spots .I am going to send my detector ahead of me and would like to play around with it while i am there.I get to go visit my wifes family and go detecting in a old area far away from Ca. so it should be fun. Thanks for any help in advance.
