I'm not sold on this concept by your description.
I think conditions were a little unusual. Also the area is a very popular tourist area. The usual forest in the middle of nowhere would have not had the same issues.
Having said all that, I usually don't venture up to Scotland until the spring.
Even the sensible Scots don't venture out ;-)
I can imagine that most Scots (inc those English living in Scotland;-) are too familiar with Arthur's Seat to bother with it every year.
I was really only in Edinburgh because half my family now live there....
Iced-up pavements and blizzards on open hill-sides = not so much fun. Whereas night-O in Culbin last Wednesday, on a clear, still night with an inch or two of snow on the ground, was about as good as it gets :-)
