I am not one for reality TV normally but this is one programme I do make an exception for. The series has just started its 4th Season run on the History Channel on Sky or Virgin. It has apparently made "stars" (in some circles anyway) of the regular characters. I think some have visited the UK.
They must have really strong nerves when it comes to driving across frozen rivers or the ocean. Not to say it is any less dangerous on the "normal" roads North of the Arctic Circle with the weather and posibility of avalanches along one stretch of road.
With the size and weight of some of the loads they take, it would be a challenge on any road let alone in the frozen wastes of Alaska. There seems to be more cross water driving this series as there are two new locations (for this series) that they make deliveries to.
