Among the events planned for Hanfordâs Flashback Festival is a 1950s-themed dance called a Sock Hop, which has roots in town going back decades. The event, which will take place from 7-10 p.m. Friday, July 30, in Civic Auditorium, takes after the Hanford tradition of Melco dances, said Hanford Chamber of Commerce President Amory Marple. She said the 130th birthday was a perfect time to bring a '50s-themed dance back to town. âThe Chamber will all be dressed up in 1950s clothes, with '50s themed decorations,â Marple said. âThe band doesnât play music as far back as the '50s, they play stuff from the '60s, so it will be a little disjointed but overall it will be a themed Sock Hop.â
