See the community parade of costumes. Ninjas, princesses and Spider-Man costumes dominated, but there was the occasional odd costume like Robin Hood, Minecraft character Steve and others.
Miles McCrudden and his family are putting the third grader together for his first mummy costume. Jessica Hoeschen, the Kindergarten teacher, is an annual hit at Valley View.
At Valley View, the parents joined in as well, see the video shorts.
If you took any video or photos, please add them, too.
