There is a lot to love about October, whose major holiday asks its revelers to hand out candy and dress up as someone else, nothing more. Even if you can’t get into the spirit, it’s impossible not to admire the folks who do. And there is plenty to admire this month—21 events in fact, to pencil in using our October Fun Map. Open House New York is a chance to see the city from a different perspective, inside landmarks and futuristic buildings like the Urban Post Disaster House; registration is already open so save your spots or pony up for a pass that gives you access to sold-out tours. The 1981 cult classic film, Stations of the Elevated, which BAM screens mid-month, portrays another side of New York, back when graffitied subways roamed, and the 1,300 bands that will be in town for CMJ Music Marathon will bring fresh music to your stale playlists. We’re very excited about the chance to gorge on oysters during Brooklyn Crab’s Fall Oyster Fest, and the release of the anthology, Never Can Say Goodbye, will remind us all why we love this city. But really, it’s all about the costumes, so start brainstorming something more viral than Ebola, HallowMEME is coming up.
