Chris - that was an enjoyable video, thanks for sharing. I like the track plan and "kid-friendly underside of the layout" planning...I thought I was the only grown man who tries to hide under the layout
I am also a fan of curved benchwork; the curves enable a larger track plan to fit into a room more aesthetically as your video clearly shows. I also had a carpenter-friend help me build my curved sections...without his help I'd likely still be working on it.
