To craft beer enthusiasts, it’s known as “pDLD.” They know that Flossmoor Station’s Pre-Dark Lord Day is a once-a-year chance to taste beers from local brewers around the Midwest. It’s also an opportunity to sample “Wooden Hell,” which has been called the brewery’s “most infamous” product. Hours of Pre-Dark Lord Day are 4 p.m. to midnight Friday, May 17, at Flossmoor Station, 1035 Sterling Ave. The annual festival includes craft beer and food sales, beer bottle exchanges and other special events for attendees. New this year is Flossmoor . . .
