They were all over the Kentuckiana area, and really good. I don't think you're allowed to open a small gas station unless you have a jar or two on the counter.
There's a burger bar chain around Montreal (la belle et la boeuf) that have this, purple Kool aid pickles. I'm personally not a fan but other people I know love them. Not uncommon.
I want to believe these are pickled body parts found at a serial killer's pantry, because the idea someone pickled innocent veggies in this nightmare is somehow more disturbing.
