Lol, before the F3 was built the Old Pac was the only way north. My Dad would play golf at Gosford, Wyong etc and as a kid I would caddy.
So every trip involved me having to fast and hold a hub cap on my lap because I'd invariably get carsick through those twisties.
Mac Pass would do it too, but traffic was always super slow since it was a dirt road then > wasn't as bad haha
