2. Balto, The Husky Who Saved An Entire Town
In 1925, the town of Nome, Alaska needed vaccines transported in the midst of a diphtheria outbreak as a blizzard raged in the dead of winter.
Unfortunately the town was inaccessible because of the winter blizzard, so mushers and their sled dogs brought the medicine from over 674 miles through remote Alaskan terrain. The temperatures were around 60 below zero, but Balto and his handler traveled through the harsh conditions to make it to the town. Because of Balto and sled dogs like him, Nome was saved from the possibility of being wiped out, entirely.
