First 3 Photos of Colac Track was Kettle Park at Barrongarook, we race there back in the 60`s and 70`s, I helped to map that track out, it was very fast track, main straight was very long, Top Gear.
The Track wasn`t Boggy Sand like Rye Reserve, Rye Reserve, was a pick of a track to maintain, Kettle Park had very good top soil, nature water springs in the bottom corner before the main straight, off camber down the back of the track. Great Track, I just loved Kettle Park, The track it still there not being used.
