Back in the mid nineties I went to a metal detector club meeting, but I don't recall their name. I believe they met off of Ridge Rd (inside the beltline) close to the beltline, within a couple miles from the mall off Glenwood. I think they met at a church or library. Sorry I cannot help more. UPDATE: I just found it on the net:
