Yes, it's true that the hour right before sunset has amazing light and it will cast everything in a warm tone with a "golden" color. But it's very tricky to take photos right before sunset…the sun goes down FAST and you don't have much time at all. There's a very narrow window where you'll have enough light. Before you know it, the sun will go below mountains or trees and everything will be too dark. If you do want to take pictures right at sunset, then I would plan the spot ahead of time and be ready. Think about where the sun will be, where everyone will be posing, and how the light will hit your subjects. The point is, when the last part of the "Golden Hour" arrives, you've got to be ready with your camera because the sun will be going down FAST and you won't have much time. Especially since you're so far north.
