Yes, we are crazy.
We spent a rather sleepless night at the refuge (Lib and I shared a blanket that our friend, Mahdi, the refuge cook, lent us), and woke up at 4:00 in the morning to begin our hike. After a small breakfast of a quarter of bread (we were so unprepared we didn't bring food, so all we had to eat the day before was some soup that Mahdi gave us), we set off in the pitch black, following close behind a friendly Scottish couple (they met at St Andrews) and their guide (yes, we were too cheap to hire a guide, but no worries, people do it guide-less all the time). We picked our way through the awkward clumps of volcanic rock using flashlights, until finally the sun rose, offering amazing views of the surrounding range.
