During my time in the mountains, I learned so much about sled dogs and their love to run. If the musher did not drive a stake in the snow to anchor the sled, the dogs would just run away with the empty sled. I think the dogs know only two speeds: resting and fast as you can run.
With only a few mushers available, most of the dogs love attention from visitors (we were warned of those dogs who did not like visitor attention). The new puppies loved the attention from the visitors.
The feeling of ice crystals hitting your face from paws digging into the snow, the wind in your face, and the awesome scenery was an incredible experience.
