My friend made the one from Eleanor Burns book and it turned out beautiful. There is a page that you can copy that explains the "supposed" code. As for me and my family we believe this
could be very valid. As was said, I wasn't there and don't know
anyone that was. There is a house about 6 miles from me that
was used to hide escaped slaves. My house was a "blind pig" back in the days of prohibition. I wish the walls could talk and tell me the history and happenings.
