I timed it for an interesting moment. I had just walked up, set my camera onto the leg overlooking the Leg, pressed record, and about ten seconds later: blink! The holiday light display turned on.
In mid-December, around 4:30 pm the holiday light display of the Alberta Legislature grounds comes to life. With a bit of the dusk light still in the air you can get a sense of the decorations. I imagine it’s even more spectacular at full dark, but (a) my camera isn’t that good, and (b) I just caught a bit of this as I was making my way to catch the train back home for the evening, and I wasn’t handing out any longer than I had to!
