Sense you asked: "due east" or north, south or west means in that specific direction instead of just "east witch refers to head in the general direction but maybe more NE or SE.
And a side note. I personally hate traction control, ABS or any other "aid" when trying to drive in slick conditions. They say it helps but I find that I can usually keep the vehicle on a much straighter line without all that crap. May just be me but if you find yourself in those conditions again you might try turning that stuff off.
Also, what's your return dat look like? I'll be headed to MOAB from Va with my girlfriend (leaving may 28) for the TacomaWorld Rock Therapy event. If we're going to be passing each other it'd be cool to get a beer!
