If you plan to hoist a pint of Guinness in celebration of St. Patrick’s Day, don’t count on the luck of the Irish to get you home safely. Don’t drink and drive, allow friends to get behind the wheel after toasting or ride in a car whose driver has overindulged. If you’re out on the town, instead designate a sober driver or have an alternate plan before you begin celebrating; most towns now have ride-share services that can take you home safely. And if you’re hosting a St. Patrick’s Day party, serve plenty of snacks and nonalcoholic beverages as well as green beer, and ensure everyone imbibing has a safe ride home.
