A detour on my way home from an engagement in Melbourne. Travelled to Tynong and worked my way around to the Four Brothers Rocks car park. Walked to the high point nearby, then returned to teh acr to set up the radio gear nearby to activate SOTA summit VK3/VC-037 and Bunyip State Park. I made 21 contacts before I closed, packed up and returned to the car. Travelled south to the Princes Highway and headed for home.
