Every Easter the Nevada Blind Children's Foundation has an Easter Egg Hunt for the boys and girls they work with as well as their friends and family. All of the eggs make a beeping sound and all of the children participate (with the seeing children wearing blindfolds).
It was one of the more unique events I've ever had the opportunity to photograph. In a way, I think the kids who had their eyesight might have gotten more out of it than the blind children.
