I wondered about that too, Kerchak. And why would anyone bring up multiple encounters on a board as full of skeptics and skeptical proponents as this one is? If I'd ever had an encounter I wouldn't talk about it here, especially if I had casts and a video. I think it's possible for the same person to find evidence, fake evidence and misidentify evidence.
I sincerely wish I'd saved Owen Caddy's illustrations. I guess I thought the old BFF would be around forever. He PMd me instructions on doing the Skookum Roll. I remember wishing I didn't have hardwood floors. I didn't know I had an ischial tuberosity until then. You can certainly feel it trying to impress itself on a hard floor.
