When I first joined this board there was a BIG OL' debate going on about the truth of UGRR quilts. Doesn't matter what the truth is (and we'll never know for sure) it's a matter of what you choose to believe. Make the quilt, enjoy it. To me, it's kind of like most stories, part of it was probably true but a lot of myth has probably been tossed in too. Once again, make your quilt, enjoy it, and build your own stories as you go.
