In reply to Slugain Howff:
Yeah, being able to see where you're going is prime... Like I said, I chose The Boar because it wasn't in the cloud. My original target was the Munro top on the side of A' Bhuidheanach Beag, but I sacked that when I saw what things were actually looking like, and also because I hadn't got up early enough.
I know what you mean about that weird feeling you get when you're skiing in a whiteout, and you can't actually tell whether you're going uphill or downhill, or indeed whether you're moving or stationary. I hate that. Feels disconcerting and dangerous to be that far out of your own reckoning.
