Because I know that if I were in these people's shoes, and I'd forgotten to bring my knitting or drop spindle along (ha! fat chance of that, but we're speaking hypothetically here), I'd be seriously ticked off. [Edited to add: A brief poll of my family members reveals that none of them would want to risk being in the car with me sans knitting. I feel this is a bit over-stated.]
As it is, I hope everyone gets home safely today.
We're just getting the tail end of the storm, and my main challenge at the moment is that our garage lock is frozen shut, so I can't get at the snow shovels. But compared to sleeping in my car during a white-out, I'm in excellent shape.
