I walked to this from the other challenges (and then realised that there was a road leading here - D'Oh). Still it was a nice walk - and my reward for going the way I did was hearing a woodpecker.
I had to wait for a van to leave. Then the GPSr took me on a tour around the stumps until I finally found it in the first one I'd tried. So I made a bit of a meal of this one - must be getting tired.
