Here in Tulsa it's Hidden Valley, but it's the packet kind where you have to mix it up yourself with Mayo and something else (I think). It's been ten years since I made any, but I remember a big packet of Hidden Valley and at least two huge tubs of Mayo.
I don't remember making it in Stillwater, but I was drinking lots of beer at the time.

Try one of the Hidden Valley packet mixes and see if that's it.
