10 !
because once i was skiing, it was the end of the season and the only snow left was on the groomers, so on the sides you had green meadows reappearing.
I was participating in a race down with some friends, the snow was slushy like never before and i decided i'd take a shortcut through a steep meadow, so i charged towards the side of the slope and skied down the meadow!
little did i know the farmer had just sprayed manure all over the grass to fertilize it ...
my friends laughed super hard at me, until they realized they had to sit on a 20minute busdrive with me :)
