Thank you for remembering and rereading it. I have one of those folders too! I added the bit about his nickname being "Spider" at Cambridge/ Night Climbers. I've always meant to include it, but forgot about the story until I rediscovered it the other day. I alway have him doing free running/climbing in a story here and there as well. That I find fascinating how someone can't run an bounce off a window sill while climbing up a building.

Amazing what human being figure out they can do.
