Putting the Skyline to one side a moment.
I believe and I'll bet IainR agrees that people (Walkers and runners) don't get the map out enough. When you need to look at a map it's usually too late. Why wait till the clags down to open the map.
The number of times I've been on a hill on a fine sunny day when you can see for miles and some one has said can you show me where we are on the map please leaves me stunned. These people aren't lost they can see where they are going but can't relate it to a map. What better time to have the map out following the terrain and practicing your skill. Even more so in bad weather. There is nothing more reasuring on a hill with inexperinced people with the clag down than saying we should pass a stream/wall junction etc in 100ms etc and then it appear a couple of minutes later.it's not magic just good practice.
I think I'll go have a cup of tea.....
