OKLAHOMA CITY — The Oklahoma Cattlemen's Association (OCA) Ranch Rodeo is taking entries for its first ever National Anthem Singing Contest through July 1.

The contest will determine the singer of the National Anthem at the Friday night performance of the OCA Ranch Rodeo on Aug. 23 at the Lazy E Arena near Guthrie.

The deadline for entry is July 1, and the top three finalists will be selected by July 15. Online voting will take place to determine the winner, which will be announced on August 1. To enter, contestants must complete an entry form and submit a video performing the National Anthem (solo and a capella only). The entry form can be found at okcattlemen.org/oca-annual-ranch-rodeo.

The OCA Ranch Rodeo consists of 12 ranch teams of 'real ranch' cowboys that compete in five different events depicting daily tasks from life on the ranch. The competition is fierce, but the cowboys don't take home much more than bumps and bragging rights. They participate with one goal: to support the Children's Hospital Foundation (CHF). The OCA Ranch Rodeo has raised more than $500,000 for CHF since 1997.

The OCA Ranch Rodeo is a two-day event scheduled for Aug. 23 and 24. Performances begin nightly at 7 p.m. and doors open at 5 p.m with shopping inside the trade show.
