It might seem a little counterintuitive at first: drink, then run — and then drink some more, run a bit, and finish it all off with a few "down-downs," which consist, oh yes, of drinking (teetotalers need not worry — water is okay too). It's called hashing, and, crazy as it sounds, it's a worldwide sport, with chapters everywhere from Boca to Baghdad. The premise is fairly simple: Every week, hashers gather in a different location and send out a "hare" to lay a trail — using chalk, flour, toilet paper, whatever — for the rest of the hashers to try to follow, shouting the customary "On, on!" to show they're on track. The wily hare, not wishing to be caught, lays various ingenious traps for the hashers in pursuit. It's not easy, but when things get sticky, the hare stops everyone in their tracks with — what else — a hidden stockpile of beer. Afterward, everybody gathers in a raucous circle to sing songs, make merry, and impose down-downs on each other. Although Miami has yet to claim a hash all its own, the Fort Lauderdale/Miami Hashers are always nearby, and they're a hell of a nice group of people to spend a Monday night getting sloshed with. For information about the next hash, call the hotline. On, on!
