I always say that living in New York is all about extreme temperatures both during Winter and Summer. In the Winter it’s warm on subway cars, over subway vents, vents on big buses, and vents from dryers for laundromats. Whereas the street in general is cold, plus subway platforms and if you’re very unlucky, your apartment. My apartment is very hit and miss with how the heat is, but only one time since I’ve lived in New York did I have a night without heat and that wasn’t at my apartment. If that were to happen again I’d definitely crash at a friend’s place because you never realize how cold it can get indoors until you have a night like that.
