7:25am -- leave house -- whole trip in 4WD, mostly geared down from 4th to 3rd or 2nd. New tires are great.
8:28am -- reach 100th Street on US-131 (Exit 72), traffic grinds to halt. They were detouring people at 142nd Avenue at Exit 68, so I could have diverted to Kalamazoo Avenue from 100th Street, but those back roads are not good. Rather stay on the highway.
9:15am -- road reopens, after I've driven a little over a mile in 45 minutes.
Call ahead to Physics Dept. and explain that the road is open, that I will be there, that since it's Thursday, I expect 1104 Rood to be locked -- could it be opened and the students told I will be there?
10:00am -- arrive in Lot 61 after a bit over 2½ hours on the road.
10:09am -- arrive at 1104, intending to launch into class... except doors are locked and students waiting outside.
Not sure what the drive back will be like. At 1pm, coming back from the Help Room, the view from the enclosed walkway between Rood and Everett showed all the sidewalks clear, but damp. At 2pm, heading to class, they were snowy, very icy and slippery. At 3pm, walking back the breeze caused the walker to slide sideways at one point. Hang on!
