Haven't lost power here in Redmond at all, just flickers last night! I did venture out to the package lockers at the front of my apartment complex a little bit ago to get a package, and it was definitely hairy. The stairs down from my front door are solid ice, as are the sidewalks, and the edges of the parking lot road. The center of the road was slush, so I walked there, but I had a lot of trouble walking up to the package locker - I actually had to grab it and pull myself towards it, because there was a very slight incline (maybe 1-2% grade) and I couldn't get enough traction to get up it.
And right there was USPS, delivering packages, living up to their motto. I definitely made sure to thank the postman, and wish him well.
