That's not a typo. This is an event sponsored by Montpelier House Museum of Laurel, MD. It is being held at the Maryland City Library since Montpelier is currently being renovated. From their description:
"Costumed Staff will teach old-fashioned tavern games. There will be live music by Bedlam, who play 18th and 19th century tavern music and visitors may even learn an 18th century social dance. Light tavern faire--all non-alcoholic--will be served. Fun for the whole family."
When I called Montpelier today they assured me that although this event would be enjoyable to adults even though it is open to adults and children.
