Winter sports take many forms of exciting , mostly very physical, activities.. Fore those who have done it all and are looking for adrenalin surges on a particularly steep slope, or frozen wasteland somewhere in the arctic, the choice seems to be endless. Heli-skiing is great , but probably no longer as extreme as all that, dogsledging though much fun, is unlikely to turn on many under the age of 21.. Have you been in an ice cave? slept in an Igloo ? hand glided on skis? gone ice sailing? how about snow kayaking? jus a few crazy ideas for the winter, or you could simply go skiing..boarding..or be pulled along in lovely scenery by a couple of reindeers or moos just loving the pristine snow all around.
