Went to a local park that I have hunted before. I went back to a spot that I have went over a few times. The first time I dug only the good sounding signals. Second time same thing. Found some silver both times. This time I dug a lot more signals that the were not very good. Came up with the following additional targets from the site. I will go back over it again and then dig the even worse trash type signals next time.
