Gorgeous video: Mention of the Pyg track and Llanberis reminded me of the day in the 1970s when 'er indoors and I plus a mate and mrs mate climbed the Pyg track from Llanberis pass: Halfway up the fog/cloud came down:
The girls freaked out but we managed to cajole them to the top: They flatly refused to walk back down the Pyg.
We managed to persuade the conductor of the last (and already full) train of the day down to take them down, but mate and I had to walk back down groping from cairn to cairn.(None of us were experienced walkers, but we did have the right gear/boots/cags.)
Molto beero /gin required to steady nerves at the bottom.
Btw what camera do you have (?attached to mast) that gives the sensational moving 360deg views?
