LB, if the Mets or the US Open don’t interest you (or it’s not that time of year) you can do some shopping on Main St in Kew Gardens Hills, eat lunch at one of several pizza stores, get some take-out and baked goods for shabbos. then head over to Flushing Meadows Park- feed the ducks, take a nice long walk around the park, visit the Queens Museum, the zoo, the site of the 1964 World’s Fair, etc. You can even visit Trump’s childhood home in Jamaica Estates.
YY- the Dodgers and a “used to have an airport” don’t count, since LB can’t go back in time. As far as 13th Ave in College Point, Queens …I don’t think it has what BoroPark’s 13th Ave has to offer. Maybe there are other 13th Aves?
