For over a century, Lake Superior has been a region for sled dogs. First as a reliable way to deliver mail, and more recently as a competitive winter sport. In fact, among the five national parks, four of them team up with local volunteers to host sled dog races. Coming up at the end of January, the John Beargrease race—the oldest and largest event--takes off from Duluth, Minnesota, headed up the shore to Grand Portage. In this episode of the Lake Superior Podcast, Walt Lindala and Frida Waara talk with veteran musher Blake Freking about the race and his passion for the lifestyle.
