One experience I would have loved to have had is golf on the Blackheath Common, the seven hole course, late in its life (1920s I believe) as the bisecting roads and pedestrian paths became increasingly busier, eventually too busy for golf. That's one of the many things I adore about golf in GB&I: the public courses littered with right-to-roam pedestrians.
I guess I would say the same thing about the final years of Leith. That would have been interesting to see an early historic course become overwhelmed by the encroachment of the area's development and commerce.
These days. St. Andrews has that aspect and North Berwick and Bude & North Cornwall. And Minchinhampton, Wimpledon, etc. I love that idea of playing on the busy common where the golf was only one aspect of the shared space. In America, we have so clearly delineated the lines between the golf property and its boundaries.
