I went with the dogs up to Mt. Caverly. last fall I was there with the mountain bike and I never thought we make it with the sled especialy down the hill. But with 1,5 feet of snow all the bumps and holes and washouts are filled and it wasn't as scary as I thought. good to have a mat brake!
All four dogs digged great even Chinook.
What you see in the back is the completely frozen lake Winniepesaukee.
For my friends in Germany: Just for comparison that lake has the sam square-km like the Mueritz in Germany. imagen the Mueritz freezes competely and you can drive on it with a Pickup truck :-)

A video of that ride will come soon.
