Like I've told several people, you find out quickly about scale when you build a layout this large. I would buy paint a dozen cans at a time, white glue by the gallons and track by the 100 pc boxes at a time. Eyes would roll when I'd talk about needing another dozen engines after just having put decoders in 6 or 8.
I guess I've just grown accustomed to the scale of things required. Is that good... or bad ??
