I still think you have a pretty good overall master plan and that has to help. I start out at one end of the layout with a wire and forget where it was going by the time I get to the other end, and mine is only 6x16.
I do appreciate your offer of hospitality, but I was just kidding about having to be thrown out. Maybe not on the questions though, but if you like them that would be good. OTOH, I might be speechless and unable to ask any. Your layout is very impressive from the pictures here, but I am sure it's much more impressive in person, it really is an amazing project.
