Secession? ‘South County’ considered it | www.mypalmbeachpost.com

Eliot Kleinberg reports this was once a serious effort. This story was in Today's "Neighborhood" section of the Post. From the article, click title for link:

Several times, the southern half [of Palm Beach County] has tried to break off. Here’s more from a two-part Post Time column in 2003:
The most aggressive attempt fizzled in 1978. In 1971, angered by busing to achieve integration, some Boca Raton residents had pushed for a separate school district in “South County.” That failed. Then, in December 1977, Boca Raton officials voted to approach eight neighboring cities and towns in the southern half of the county. They proposed splitting off at the Lantana-Lake Worth line and due west.
The split would require an act of the state legislature, probably followed by a referendum by either the entire county or just the part that would secede.
The southern half, which accounted for about 40 percent of the county’s area, fumed it was an ignored stepchild of the county seat, West Palm Beach, and victimized by a sprawling and unresponsive school district and unfair tax distribution.
