Not OP, but I’m from the Midwest, and I find your “must be a California thing” hilarious given that we were eating a Honey Baked Ham at least once a year over 40 years ago. Imagine my surprise (and regret that I had since gone vegetarian) when I moved to the west coast and found a Honey Baked Ham store in Bellevue, WA. My wife still gets one once in a great while, and I’d be lying if I said I didn’t sneak a piece or two.
Anyway, back to the point, looking their website prompts me to ask where one would have to live in the U. S. and not be within an hour’s drive of a store.
