This Wacky Pack came out in 1973; it's been mine since new. Wow, I don't want to stop to count those years. Anyway, Rice-A-Roni does have its origins in San Francisco and was first produced in 1958. Here is a Wiki link if you desire more Rice-A-Roni info for some strange reason.
I can still remember those old commercials with the trolley cars, can you?
