My snow-walking days are over - I just sold a pair of snowgoggles on eBay - eight quid! But looking at the mazes of antiquity page I was struck, again, by the image of an emergent mushroom. Give someone a few hallucinogenic mushrooms, put them at the centre of a maze, and it'd take them ages to find a way out.
On another slant has anyone else slept on the tor, or is it just I? It was only once, summer solstice night, and there were others up there, staying awake.
