Growing a mountain! Delia, using colored mastic seals the surface of the mountain. Note the foamed seam where a piece had to be added. That seam was then trimmed and mastic-ed over. Meanwhile Clarke is figuring out building placement on the layout, which you'll notice is without the mountain for the moment. And a look at the control area, And no smarties commenting on the incorrect controller on the right. This is a only a photo-op demonstration.
While this has been going on, Roy has painted the base and Mike, who you sort of see under the layout, is wiring away.
