Just Wondering

So upon ascent up the mighty Berthoud Pass last Wednesday morning, I spied a helicopter obviously circling and searching on the steep slopes of the formidable mountain.  We pondered a host of situations that could lead someone to be caught with their ski pants down in the backcountry.  We passed Search and Rescue trucks, Sheriffs, and more cars that hinted at an active search.  Wow!  This is exciting in a horribly life/death kind of way. 

So naturally, the next day I went on the web to get the low down on the situ.  And indeed I found an answer, only to net more questions.

Guang Ming Lang, a 26-year-old Chinese citizen who speaks limited English and is a graduate student at University of Michigan, “left the top of Berthoud Pass at 6:30 p.m. (Tuesday) with no snow travel equipment, no food, no water, no map or compass, no light source and wearing light-weight clothing and low-cut boots,”

These are my questions to the crazy Chinese dude.
First one.  Graduate Student?  Really?
Second.  6:30pm?  In the dark?
Third. Were you on meth?
Fourth.  Are you receiving psych meds for this problem, now?
