Around 1973-74 as a teenager I was in Boston Massachusetts and this being just before the 1976 Bicentennial the city had a walking tour to some of the historic sights. You followed the painted yellow footprints along the sidewalks to various historical sites. This walking tour lead you thru some of the less desirable parts of Boston. In the "good life" department Boston put New York city to shame at least back then. This experience was my yard stick for what I considered urban/societal decay until about 1985 when I was in Seattle. Wow what an eye opener Seattle was almost forty years ago. So, I had a whole nother yard stick to go by after 1980's Seattle. Fast forward another decade and I was back in my home state of Florida in 1995 up around Hobe Sound for six months. Before there was the interstate highway Florida was a neat place, things have been pretty much downhill ever since. Anyway, I had cause to be down around the Miami/Fort Liquiordale area and the homeless camps under the Highway overpasses were amazing to say the least. A whole third world society right there. In the early 1980's following the ongoing Haitian refugee crisis and Mariel boatlift it never approached anything like those camps. It's sort of unreal the exponential growth of this, it seems to be snow balling at a huge rate.
