On his doctor's advice, Robert Louis Stevenson spent two winters in Davos. He finished Treasure Island there, but didn't like the place:

'Shut in a kind of damned Hotel,/Discountenanced by God and man; /The food? – Sir, you would do as well/ To fill your belly full of bran./The company? Alas the day/That I should toil with such a crew,/With devil anything to say,/Nor anyone to say it to.' 'So,' according to E.S. Turner, 'RLS took to tobogganing, alone and at night, which he found strangely exalting.'

I made my first trip to Tibet in 1987. One of my companions was a former British army officer called Garry Daintry, who told me that during the winter he helped out on the Cresta Run in St Moritz. The Cresta is an ice chute that you descend on a ‘skeleton’, a toboggan that you lie down on head first, and which has neither brakes nor any steering mechanism. You can try to control the speed by ‘raking’, rubbing the spikes of your special shoes on the ice, but you will inevitably reach speeds approaching sixty miles an hour.
