Starting Monday 11/20, many light/winter installation started showing up through out the city.
I walked by Amazon's Day1 Plaza Monday noon-ish, and sat in one of these domes, fit with a rocking chair, led light and soothing music. This is part of the Winter Wonderland in South Lake Union.
In the evening, it looks even prettier, thanks to the glowing dome.
Westlake Park puts up a lot of lights. The Star at Bon Marche won't be lit until Black Friday.
Throughout the Thanksgiving week, Seattle Center's Armory is putting up Xmas decorations.
Many large and small Xmas trees, dusted with fake snow.
The best is the miniature village with 2 running train tracks.
New this year (maybe only new to me), you are allowed to control the train at certain time slots.
