In what city's borough would one find the neighborhood in which the "electric park" which inspired many others is  located in?
Electric Park Electric Park was a name shared by dozens of amusement parks in the United States that were constructed as trolley parks and owned by electric companies and streetcar companies. After 1903, the success of Coney Island inspired a proliferation of parks named Luna Park and Electric Park, while the World's Columbian Exposition of 1893 inspired the formation of White City amusement parks at roughly the same time. The existence of most of these parks was generally brief: the bulk of them closed by 1917, the year of the United States' entry into World War I. Many pavilions have outlasted the parks themselves, with a few of them still standing today.
Carnegie Hill Carnegie Hill is a neighborhood within the Upper East Side, in the borough of Manhattan in New York City. Its boundaries extend from 86th Street on the south to 96th Street to the north, between Fifth Avenue (Central Park) on the west and Lexington Avenue on the east. The neighborhood is part of Manhattan Community Board 8. In the 2000s, the perceived northern boundary on Park Avenue has edged over East 96th street into what was traditionally Spanish Harlem, leading to that area sometimes being called Upper Carnegie Hill, especially by real-estate brokers. According to the official Carnegie Hill Neighbors website, Carnegie Hill extends from 86th to 105th Streets (between Fifth Avenue & Madison Avenue), but not including, Third Avenue.
