Started the trek up from Selo (1582m) at about 11pm, reached summit just before 5am. Spectacular view of Merapi smoking and the twin cones of Sumbing and Sundoro in the West.
After spending about an hour at the summit, went down the same way and reached Selo in about 3.5 hrs.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
