Climbing down into a deep dark hole

Heads up. I will be dissapearing into a deep, dark hole, effective immediately.  I will emerge, with sanity intact (we can hope) after Friday. 

Friday is a 3 hour, comprehensive midterm, that will test material through this week.  There's a lot to do between now and then, and for the first time, I am feeling my commute.  This week is the worst, back to regular scheduled programming soon!
