The city line appears to pass diagonally through this house, which has two different addresses posted beside its front door: 87-101 257th Street (Queens) and 1 Keene Avenue (Floral Park in Nassau County). Keene Avenue is an odd little roadway. It's the continuation of 257th Street from Queens into Nassau, but it only runs for maybe 50 feet before it crosses Jericho Turnpike and turns into Garfield Avenue (which itself lasts only another 300 feet before coming to an end). Google Maps doesn't acknowledge the existence of Keene Avenue, but check out Street View. You can see a Keene Avenue street sign on Jericho Turnpike, and you can also see where the newer Nassau County pavement ends around the city line, which gives you a good visual sense of how ridiculously short Keene Avenue is.
