So here are pictures from the 10th anniversary of MK - so 1981. I see a few trees in planters, and not a whole lot of others. It took a long time for them to grow in. They weren't planted to be 50 feet tall and bushy.
Here is a picture from 1985
Still not seeing the view that people are spouting off of the hub being a tree filled utopia. I see planting beds, flowers, bushes, and a few small trees. This is what it really looked like back then. Memory is a funny thing. We all think we remember, but mostly we are remembering the good things, and not the bad. With today's web and social media, we no longer forget, because we can google it now.
