Full seafaring attire is mandatory at this pirate-themed bar crawl, so don’t bother turning up without a cutlass, peg leg and talking parrot on your shoulder. (Those who do not meet the head-to-toe sartorial requirements will be booted out of the crew.) You’ll also be expected to talk like a bandit of the high seas; we suggest you bone up on your buccaneer lingo on International Talk Like a Pirate Day's website (talklikeapirate.com). PirateCon is free to attend, but bring plenty of cash for rum and beer, and have a MetroCard handy (or hooky). Keep your one good eye on the website 24 hours before the event, when the treasure map detailing your route will be revealed.
