Well, we've made it to the far edge of this (ridiculously scaled) diagram! That means that here in the Northern Hemisphere, the days, after today, will start to get longer again. That, is something worth celebrating.
Those of you in town tonight should all come out to see the Kensington Market Festival of Lights! It's their 20th festival. It never seems like the year is really over unless you've lit something aflame.
