The Mabry-Hazen House staff will host friends, board members and members of the public to celebrate over three decades of historic preservation and education. The event is a swingin’ 1920s garden party and will feature: a silent auction; costume contests for the best flapper, mobster and silent film star outfits; open bar with signature cocktails, local beer and wine; heavy hors d’oeuvres; dancing tutorials for swing and other 1920s dance styles; live music from the Old City Buskers; and historic house museum tours. The event will raise money to support several capital improvement projects.
