If I may ask, how long ago did you grow up around this area?If it helps, as I look on a current subway map for stops and see that three diff subways stop at three diff Kings Highway stops, I believe I was on that one that did the Parkside, Prospect, Church, Newkirk, Avenues H,J,M. I skipped a few, but you get the idea.
What I meant when I was asking what area this is, is that people refer to areas in Brooklyn as Sheepshead Bay, Sunset Park, Bensonhurst, Midwood, etc..
Maybe this area is like Midwood or Sheepshead Bay, or just known as Kings Highway.
Anyway, very cool that someone had an idea what I was even trying to remember!
is the current MTA map. I don't see a Kings Highway stop on the D, although it surely stops around the area you're talking about. Now according to A9 (the Amazon.com mapping program, a free download and by far the best of the map programs) the area is called "Gravesend". Here: http://maps.a9.com/?ypLoc=Broadway%20and%2046th%2C%20New%20York%2C%20NY
but it's probably just as easy to download the A9 yourself.
Personally, I'm Manhattan born-and-bred, so this is all the stuff of legend and B movies (e.g., "Warriors", "Murder, Inc", "Saturday Night Fever")to me.
Do you think I might have too much time on my hands this morning?
Hope this helps.
