Starting today, users of Field Trip for iOS, Android and Glass will be able to experience some of New York City's forgotten -- and occasionally creepy -- locations as Google's Niantic Labs brings Abandoned NYC's content to the app. Normally, Field Trip functions as a convenient mobile tour guide, delivering interesting information provided by sources like the American Institute of Architects and the Little Black Book series. With Abandoned NYC joining the ranks of content providers, Field Trip users will be able to explore obscure, mysterious and atmospheric spots across the five boroughs uncovered by photographer and project founder Will Ellis, like Harlem's Public School 186 and the Red Hook Grain Terminal.
