The Q at Parkside
News and Nonsense from the Brooklyn neighborhood of Lefferts and environs, or more specifically a neighborhood once known as Melrose Park. Sometimes called Lefferts Gardens. Or Prospect-Lefferts Gardens. Or PLG. Or North Flatbush. Or Caledonia (west of Ocean). Or West Pigtown. Across From Park Slope. Under Crown Heights. Near Drummer's Grove. The Side of the Park With the McDonalds. Jackie Robinson Town. Home of Lefferts Manor. West Wingate. Near Kings County Hospital. Or if you're coming from the airport in taxi, maybe just Flatbush is best.
