Bamboo forest

There is a clear ridge line between our Yano town and Kaita town. By some maps, there is a road which cross the ridge line. I thought to climb over the ridge line. And decided to do it today.
After I enter the forest, the road disappeared. At first, I tried to go bamboo's bush. But, I abandoned soon. The reasons were that the surface of ground was very wet, many mosquito attacked me, red mark of road was deleted, and the slope to be hard. Perhaps, nobody walked there for a long while.
GPS showed that I could't reach to one third of distance to ridge line. I'll try to reach the line from another route someday.
