The weather is still cold enough to hit the snow for some fun and speed.  Race in the Snowmobile Winter Racing challenge and see if you can control your snowmobile and get to the finish in first place.  Of course you want to win but you also can"t damage your snowmobile.  Damage that you get to your snowmobile or your driver, especially the head will really hurt you.  Race fast and unlock more powerful snowmobiles.
