Addresses in Queens are notoriously confusing. Bar 43 in Sunnyside, located on 43rd Street at 43rd Avenue just a block off Queens Boulevard, is certainly easy enough to locate (GMAP). But navigating to Sunnyside Gardens Park on 39th Avenue, further north, may deliver you in a state of panic as you find yourself passing 39th Drive and 39th Road along the way (GMAP). How do you make sense of the repetition of street numbers? What is the logic behind it?
