I presume you mean navigating in fog. Well as to following a bearing, you simply find it and walk, and of course check regularly to ensure you are on course.
Usually it's easy to tell where you're going in mountainous terrain, as you simply need to study the map carefully and you can tell which way you're going.
I hope you are not thinking that this is it and folk go out on your advice. A bearing only works if you know where you are when you take it ! And the compass has not been effected by anything.
I'm sorry but navigation, especially in cloud, is not as simple as you make it out to be, especially in winter on hills. A gps can be a lifesaver FACT.
