I attended the same program #1Piecemaker did in Ashdown. I had already heard that the story was fiction, so I listened carefully to how they presented their information. When they introduced their program and before presenting each block they reiterated that this was oral history taken from "Hidden in Plain Sight". So they did not present this as the gospel. There have been many things thought to be myth then later found to be fact. One was that of Jefferson having black children. Only recently with DNA testing it has been proven to be fact. I don't know if the UGRR quilt story is fact or not, but I do believe it could have some truth to it. It's true that most of the slaves travelled at night. But when it was white ministers or other white sympathizers conducting in the daytime the quilts could have been markers. Who writes history? usually white men. This story is black oral history and is basically a woman's contribution story. I think it could have happened. In the history of WWI and WWII codes and marking were used to signal safe houses. Why would the UGRR be any different?
