The publicity seems to be ratcheting up about the Big Mac's middle-age celebration (

) in the US, particularly in it PA birthplace.
I can't recall home long the chain has been
here - maybe 35-40 years?
:-:Happy 40th Birthday,
Big Macca!:-:
I would guess I could count the number I've had in the past year or two on one hand or one finger. It's strictly 3AM snackfood on the way home.
As the Australian McD HQ is a walk away from my home, I suppose I'll wish it a happy birthday - as I walk or drive past.
Do you know anyone who made their fortune from big Macs?
