Why are Uncle Ray's potato chips not sold in California?

I'm curious, could you please explain why Uncle Ray's potato chips seem to be absent from store shelves in California? Are there any regulatory hurdles or distribution issues that have prevented them from entering the state's market? I'm particularly interested in knowing if there's a specific reason behind this, or if it's simply a matter of prioritizing other regions for their products. It would be great to get some insights into this apparent absence from the Golden State.
