re: Building scale models and shipbuilding museums: $$$. We should probably still be building ships here, but you can take that up with Irving and the union at the time if you all so desire.
re: Uptown comparison: First, thanks for using my photo

Second that's quite a change considering that the city's population is more or less the exact same (or even less) than it was in the 1980s. When it was torn down I was really sad to see the Y go but the law courts is
such a large building that it almost makes up for it. One thing that Helladog forgot to mention was the Tile Mile!

The Mercantile Centre also fills in a good amount, as well.
You can see how much the trees have grown in those ~30 years. In the 80s you could see the Gothic Arches over the other buildings on the left but the trees have grown so that view is obstructed. You can also see this with the trees below the Red Rose Tea building.
