BRRRRRR (or How 3" of snow can shut down a city)

So while I was sleeping on Sunday it snowed. A bit. Like 2-3". Not bad, unless you live in the Portland Metropolitan area. This is enough to shut the city down for at least one day. Totally. I still went to work that night, without the legally required chains. I didn't know, and fortunately, I didn't get caught. Now I know to check the ODOT site during inclement weather. Now I have chains in my truck. Now I'm staying home as much as humanly possible, because, Baby, it's cold outside. Good for knitting, bad for pretty much anything else you might have in mind. Oh, yeah, and it means the heater is now turned on. Household temperatures in the 60's, not too bad. Temps in the 50's, wrong, very, very wrong.
