Itching Tree, Idaho

The town was named Itching Tree because when the first settlers arrived, one of the trees was covered with poison oak and poison ivy.
Anyone who got near it would itch for days, even weeks. Only one out of several trees was contaminated.
The people tried everything to rid the tree of the poison, but nothing seemed to work. Then one day, almost six months later, magically the tree was clear of all signs of the poison.
No one knows what happened. It seemed like a miracle had happened overnight.
