Came Up to Watch the Sunset

When they got to "the top of the ridge" and Kody said they can watch the sunset from there through the trees, then production flashed to a grove of thick trees, I almost spit out my coffee laughing. Then after their pathetic conversation (which I may comment on later), he said, "ok, let's get out of here before it gets dark..." I was again laughing out loud at the ridiculousness of them both. I mean, were they unaware that sunsets happen right before it gets dark??
