There’s nothing like an element of mystery to spice up a romantic evening. Partygoers don optional costumes or black-tie attire for the Valentine’s Masquerade Ball, a sweethearts’ soirée presented by Vermont Gatherings. Hors d’oeuvres and a cash bar propel an evening of dancing, door prizes and live entertainment for singles, couples and groups of friends. For those seeking insight into their love lives, New Hampshire father-daughter psychics Lord Fafnir & Spawn purvey tarot readings. Vintage Photography Emporium offers green-screen photos to help revelers memorialize a night to remember.
