As our month dedicated to "Milwaukee Regulars" continues, we head over to the Knights of Columbus banquet hall for their weekly bingo night. You’ll meet some of the dedicated regulars, including one who has faithfully attended for an impressive 30 years. Then we sit down with Dan Castle, the banquet hall’s manager, as he unravels the secrets behind the night’s enduring popularity and the factors that have contributed to its loyal and enthusiastic following (spoiler alert: It has to do with winnings).
