From a Salt Lake newspaper: Fry sauce is just always something we've had. Even McDonalds used to carry it. I can remember the first time I went to Las Vegas and we stopped at a McDonalds and when I asked for fry sauce the employees were dumbfounded - they'd never heard of it. McDonalds stopped carrying it, even in our area, about 10 years ago, but it is prevalent in almost every other restaurant in our area. Yes, I realize you can make your own, but mixing ketchup and mayo together isn't always what it's made of. Does your part of the country have fry sauce?
