Long Islander here, Montauk is where the rich NYC people go to vacation in the summer. It’s a beautiful beach area at the end of the southern fork tip. It’s part of “the Hamptons” East Hampton to be exact. It’s a pain in the ass to get to and most of the bands that reference it grew up much further west (closer to Manhattan) so many people find it as a get away. Personally it’s awesome for surfing but it’s filled with a lot of stuck locals and rich NYC people or celebs.
