In what city's borough would one find the neighborhood in which the "electric park" which inspired many others is  located in?
Coney Island Coney Island is a peninsular residential neighborhood, beach, and leisure/entertainment destination on the Coney Island Channel, which is part of the Lower Bay in the southwestern part of the borough of Brooklyn in New York City. The site was formerly an outer barrier island but became partially connected to the rest of Long Island by land fill. The residential portion of the peninsula is a community of 60,000 people in its western part, with Sea Gate to its west, Brighton Beach and Manhattan Beach to its east, the Lower Bay to the south, and Gravesend to the north.
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.
