Best Day of Detecting After Reviewing Old Maps

Over the last few months, I have been looking over old maps like Gandalf searching for the secrets of the ring in Minas Tirith. After some careful research, I discovered an old footbridge dating back over 200 years that no longer appears on maps after the 1900s. I decide to detect where the bridge should be and the path leading up to it, and to say that day was unforgettable would be an understatement!
