You are absolutely correct Iron - In fact, that is one of my secrets, or used to be. I would follow tornado's damaged areas. One great story is in Austin Minnesota at Todd Park. There must have been 30 huge oaks knocked down in the park. I detected each tree and found some great old coins. The best being my first silver dollar 1926, and a silver half dollar. Good luck and let us know how it works out come Springtime!
