Families can look forward to a frightfully fun evening in downtown Bethesda as Bethesda Row hosts its Annual Halloween Trick-or-Treat Event on Thursday, October 30 from 5:00 p.m. to 7:00 p.m. The event promises a mix of community spirit, festive fun, and local giving, with all proceeds benefiting Manna Food Center, the Montgomery County nonprofit dedicated to ending hunger.
