Hal, Were the two stones granite and SANDSTONE? The granite part is easy. The sandstone is trickier. I saw an outcropping of it behind my back that night while standing on the site of the Octagon. I'm from Minnesota and we ARE sandstone, so I thought it was a bit unusual to see this red sedimentary rock amide the igneous granite all around. Do I win?
