Yeah, probably has more do to with proximity to at least a B tier grocery store. If your local grocer is Target, Walmart, or Family Dollar, then you’re only going to have access to the vegetables from Veggietales and bread from a plastic bag.
They grow naturally where I live. Not the giant ones like Farfetch'd carries, but when I was a kid, I loved digging them up in the woods and just eating them raw lol
I think that's a local thing. My grocer carries them, and they're always in stock. I line in the Midwest. But I seem to remember eating them a lot in Oregon, too?
