Redwood Acres Event Center is a venerable Eureka institution situated on 52 acres near the north end of Harris Street. It first opened its gates in the fall of 1937 for a local agricultural exposition and horse racing; admission to the fairgrounds that year was 50¢ per person. Today auto racing has replaced horse racing, and the agricultural expo event has given way to a full slate of events that include The Best of Humboldt Fair, Humboldt Roller Derby, Humboldt Artisans, Humboldt Sponsors, Redwood Flea Market, NCIDC Intertribal Gathering, Antique Show, Local 4-H, F.F.A. and Junior Livestock Association Shows, Rose Society Show, Quilters Guild, Gem and Mineral Show and Mushroom Fair. The auto racing takes place at Redwood Acres Raceway, a semi-banked, 3/8-mile paved oval racetrack with a vintage covered grandstand and lighting for nighttime racing. And the horses haven't gone away entirely — you'll still find an Equine Center with eight barns, four arenas, a round pen, 164 stalls and 77 turn-out pen spaces. This place is jumping!
