Why did Don DeFore leave the series??
In all the decades I've watched this show, I've never found an answer to
this question. Thorny just stopped appearing after the first four years
or so. I always wondered if DeFore had a falling out with Ozzie, but
he appeared with Harriet, Mary Jane Croft, David and other TV cast
members for a 1981 Christmas special. He was very amiable and loved talking
about his role. But nothing about why he left! Does anyone else know?
