Happy Father’s Day from Rides a Bike: Don DeFore, best known for his longtime role as “Thorny,” the Nelson’s friend and neighbor, in The Adventures of Ozzie and Harriet, tricycling around a decade earlier with his two kids, and a new movie — Too Late for Tears — to promote.

The Inside Hollywood by Nat Dallinger caption reads: “On a bicycle built-for-one, film leading man Don DeFore joins his two children, Penny-Lu, 6, and David, 3, for a spin around the driveway of their Mandeville Canyon Home. In his latest screen effort, ‘Too Late for Tears,’ the actor turns dramatic for a role which finds him involved in murder. A graduate of the amateur stage, Don’s screen career is now in high gear.”
