I ran two ten dog teams by myself last night. It was raining hard, and cool. The dogs worked hard, pulling the machine through the grassy fields and leafy woods to the turnaround and back again. Even in the rain they get pans of water at the end of the run. They gulp it down quickly and wag their tails as I walk by. The batteries in my headlight were old and the light was too dim to work by so I keep the machine running as I hooked up and unharnessed. I fed the dogs and went home wet but happy.
