I had to measure the distance between this poles
The view on the top of tunnel
Crested serpent Eagle - There are Black Eagle and Crested Honey Buzzard too seen at this site. Hopefully more to be seen in my next visit
My motorbike does not betray me for this long journey (450km return).
Well, I'll come to this site once in a two week (I only wish that I can came more frequent and got some place to stay)
