Good morning. As you’d expect, quiet, as reinforced by this tweet from the WSDOT person watching metro-area highways:

Every Who down in Whoville, the tall and the small, were singing because there's no traffic at all. My heart is growing 3 sizes!

One more reminder that the holiday schedule changes start today for Metro riders, as outlined here – today it’s the “reduced weekday” schedule.
