Producer's Dairy is an independent, Fresno based dairy. The owners are the Shehadey family, who lived next door to my family when I was growing up. I had lots of mock gun battles with the kids.
The spokesperson for Producers is Hopalong Cassidy. It still says "Hoppy's Favorite" on the sides of Producers milk cartons. I remember looking at the milk cartons one time in the Country Boy grocery store, sometime in the early 80s. My dad said that Producers would have a hard time convincing young people to drink their milk with Hoppy as their spokesperson, because no kids knew who he was. He suggested they switch to Michael Jackson.
