Had a day off and a little warming of the weather so gave it another shot. I went to a park that is more wooded and the ground was definitely diggable. I think I only passed on one signal where the ground was a little stiff. I dug 1 signal that was terrible but turned out to be a Merc and I could not locate anything in the hole that was causing the poor signal, maybe it was laying funny. The big surprise was a super strong signal that turned out to be a Ben Franklin, not sure how I missed that signal (maybe it was too good). Managed 3 wheats as well. Enjoyed the bonus hunt even without the silver but that certainly was a great bonus. Wisconsin Digger
