It would make sense that someone could find a quilt in a hidden space, barn or old house. They were a way to give comfort when lying on a wooden floor and to keep you warm. There have been a lot of antiques and money hidden in walls of old homes. Ridiculous to think that anything "left behind" was part of a travel conspiracy message among slaves. What would it be....it was hidden....then the quilt would tell them, what?
There is just too much information debunking this story. It is a story, not historical fact....even the authors say that it "could be true"....NOT. Don't try to change history. Just because something is in a museum, doesn't mean that explanations are true.....case in point, visit the London Museum sometime. They have a display of an Armadillo from Texas stating that they are a very poisonous animal. Had to laugh at that one.
