And again and again and again I have to remind myself that a nice day is one with pale clouds, with lots of daylight suffusing the air, and you aren't going to get sunbeams -- still less moonbeams -- and the whole quality of the light will have changed.
Send in a tourist, of course, and you can have comparisons. Or even a local who's been away, though there the POV will merely be aware that it's not always like that. As long as you remember. . . .
Not quite bad as putting the characters underground and having them see just fine without a light source, but still can be annoying.
