I try to avoid going into London, but usually have to go in at least once a month. Lived there for years and years, well in an outer zone, but one that changed beyond recognition. I accept that places change over 30 years, but in the early times I used to see it go up and down, by the time I left it was probably going downhill for about six years.
Generally, I’m in the City when I go now, which I imagine is the most pleasant part. I do have to go into Westminster soon. Not sure what to expect.
