Signs alerted me that I was approaching a raceway on my left as I walked toward the Mountain Dew Race Park on the edge of the tiny settlement of Sorell Creek (which is located closer to New Norfolk than Granton). Photos on http://www.mountaindewiceraceway.com/ give an indication of the types of vehicles which race on this circuit. It was all quiet as I walked past, and looking at their events calendar it seems no races are scheduled in the future.
A bus stop for the Derwent Valley Link bus service is located on this part of the Lyell Highway.
It was the rows of poplars changing from summer green to autumn gold that I will remember most. Absolutely stunning.
