Yeah, I follow some people on YouTube that I thought they were on their way to a so called completed ( I know NO such thing ), ONLY to find out about 3 out of the 4 of them have just recently started to tear down their layouts and Start all over again. I mean they did a lot of work to get them where they were only to end up not liking them in the end. Well one, Mike Fifer, actually having a new building built for his this time. But he has gone through many versions of it even when it was in his garage still. And he said recently, he enjoyed the building the most of the hobby. Dave also is starting over after he gets back from vacation in Italy or somewhere
