In reply to Sophie G.:
As you infer, just 'cause you look like something out a TGO feature article, it doesn't automatically confer mountain sense on you.
Some winters back, as one of a group of local students, we went up onto a quieter part of the Carneddau in search of sledging snow, equipped with fertiliser sacks and estate agents 'for sale' boards. These items apart, most were not dressed for the mountains in the manner of fully experienced rambling hikers. Looking for suitable snow, we trudged higher and yet higher, disappearing into thick clag long before we found a spot.
In that moment, I sensed, more than saw, a figure just beyond us, and began to focus my attention there, gradually aware that it was something more than one person standing still. As 'they' hadn't moved for some time, I went over to investigate, and offer help if needed. I noted that the 'leader' of the 'shadows' seemed unaware of my approach, and appeared engrossed in trying to stop himself being garrotted by the cord of a mapboard which twirled about his neck in the wind . I asked one of the others if they were OK, as they looked cold and dejected. At that moment, the leader, fully clad in top end mountain gear, startled by the voice, looked up.
It was a pure 'Captain Mainwaring' moment- the look of total disdain as his gaze registered my apparel of boiler suit and wellies, and the 'for sale' board I held at my side. Just at that moment my fellow sledgers made their presence known as they shot noisily into the view of this 'all the gear, no idea' leader. Even though he had yet to free himself from the menace of the twirling mapcase, he looked appalled, and hurriedly marshalled his group away.
We met up with them later, lost. One of his followers told us that he had taken them to a remote part of the mountains to teach them navigation.
