What the heck is boxing day??
Cochrane trails are the best in the world. You could drive 100mph+ on most of them. They are always as smooth as a pool table. From Cochrane to Hearst is my favorite, and there is a trail east to Quebec that is 110 miles, and you probably won't see another sled. Timmons has a fantastic club with the most beautifull exotic dancers you will ever see. I suggest the North Adventure Inn. It's outside town, great reastaurant, bar, and rooms in the same building. They even have igloos that are cottages.
Now for the bad part. It is a long drive on 2 lane roads. No freeways. I don't know where you live, but it is a long drive. If you are going for sure, email me,and I'll give you some tips.
