Long Island
Geographically, Long Island consists of of four counties, Kings (Brooklyn) and Queens, part of "the city," and Nassau and Suffolk. Colloquially, every New Yorker who says "Long Island" or "the Island," means Nassau and Suffolk, which have a combined population of 2,846,241. When I lived there in the mid to late '60s, Suffolk County was still the second or third biggest potato farming county in the U.S. with lots of wide-open spaces.
