The Columbia Chamber of Commerce will hosts its 35th annual Fiddle and “Bango” Contest from 10:30 a.m. to 5 p.m. Saturday at the Columbia State Historic Park gazebo on Main Street.

The Fiddle and Bango Contest — so named because in its first year a printing error misspelled banjo — is an open, juried contest for both amateurs and professionals, young and old. Up to 50 contestants compete in seven categories including fiddle, banjo, vocal, guitar, mandolin, miscellaneous and original song, with prizes ranging from $15 to $50, and with a grand prize of a golden nugget.

Entries are $15 for each category entered and are accepted from 9 to 10:30 a.m., at which time performances begin.

Spectators are encouraged to arrive early to get the best seating. They are also asked to bring lawn chairs and sunscreen, and to be prepared to hear both polished musicians and performers making their debuts.

This year the chamber will hold raffles as a fundraiser in place of the usual chili cook-off.

“The chili cook-off gave visitors a taste of Columbia from just the eateries, whereas the raffles allow almost every business in Columbia a chance to share the love,” said event organizer Mike Keene. “It’s a fall day, our most beautiful season, and the music is free and fun. Plus, a chance to witness a seasoned adult player try to follow an 11-year-old who has just nailed a tricky fiddle tune.”

Columbia will also host the annual Poison Oak Show on Saturday. This event allows gardeners and eccentrics with a sense of humor to enter their “floral arts” featuring poison oak. For more information on these events, call Keene at (209) 536-1329.

Additionally, Columbia’s 33rd annual “Harvest Festifall” is set for Oct. 14 to 15.
