ROCK BRANCH, Iowa (AP) – Friends and students of a retired teacher have begun helping him recover from tornado damage at his home in northwest Iowa. Nine tornadoes struck northeast Nebraska and northwest Iowa on Friday, injuring at least 15 people.

The Sioux City Journal says that on Sunday, two buses carried about 50 students, staff members and parents from Hinton High School to the rural Rock Branch home of Wayne Stadler and his wife, Debbie. One of the twisters had ripped off the roof of their home and destroyed their barn and several sheds. The Stadlers weren’t injured.

Wayne Stadler had taught at the high school for 32 years. The damage was almost overwhelming, but the hard work by his friends and former students gave him a good start on the cleanup.
