I've been to the Grand Canyon many times but have never been there when a full moon was rising. Because of the snow on the ground, it took on a very eerie look. It was a bit frightening, too. With the darkness, you couldn't see the edge and there was no guard rail ... just a short wall. Plus there was so much ice that walking was a challenge. Even though the path was well away from the edge, I made it a point to walk on the side that was the furthest from it. Things looked much different in the morning!
