Read this excerpt from Susan Butcher and the Iditarod Trail.
On January 29, Edgar Nollner waited in a dark cabin at
Whiskey Creek, close to the halfway point. Suddenly he
sat up. Bells! Was he hearing things? He ran to the
window and found that it was Bill McCarty, who had tied
sleigh bells to his dogs, coming in from the Ruby relay
cabin. Mushers, either by choice or in some towns by
law, often tied bells on their lead dogs to warn people
they were coming up behind them. Edgar had not
expected to hear Bill's bells for several days, but he
wasted no time. He took the serum and started north
along the frozen Yukon River.
