For how long was the kink between the current Turns 3 and 4 there?
I only just realised how many circuits opened in the 1960s: Winton, Calder, Lakeside, Mallala, Oran Park, Sandown, Surfers International, Symmons Plains, Warwick Farm and Barbagallo to name several. It's great to see Winton still going strong given that we've lost or come close to losing many of the others.
