A decidedly personal, but also informative take on the re-zoning. He ends with this:
At least in 20 years I'll be able to walk by and point out my "childhood home." It should look the same, since it's in an R6B area. But the community won't be the same, and I probably won't be too interested in meeting the people inside.
Are there any neighborhoods in Brooklyn where the neighborhood hasn't changed (much) in 20 years?
