Don’t worry about the dark Phoebe! I ride by moonlight a lot. It can be quite beautifull , especially after a new snowfall. The snow wll amplify any available light. Horses and I’m sure unicorns, have excellant night vision, and can see quite well wtih just starlight, and moonlight is as good as full daylight for an equine. Didn’t Marigold say she glows in the dark?Once you learn how to balance properly you can ride hands free. Hanging on to the mane does not cause an equine any discomfort, she’s just teasing you Phoebe. You can scratch and knead the skin at the root of the mane, most equines find that very pleasurable.
