The chance to grab 2 CGA Trig plus a GC cache was too hard to resist, so despite the forecast thunderstorms, set out on the track to the top. Walked up to the Cotter Dam lookout, then up the road and a side road shortcut. Bit warm in 28c heat and steep in places, stopped to sample some of the blackberries on the way. Trig soon reached plus it's smaller neighbor and the nearby GC cache. Back down before the rain hit.
