Inselpeter-- you left out one of my favorites--

All you Homer Simpson fans know it-- Flushing Meadows!
It was the sight of both of NY's world fairs (1939 and 1963)-- but Homer's image of it was priceless!

It was a "salt water marsh" that got improved into a park-- (the swamp was filled in with the cities coal ashes for 30 years or so) but Homer was in desperate need of a bathroom when he saw a bus headed for the location..

He didn't think of the Town of Flushing.. but other thoughts entered his mind!
