where I grew up there would normally be about two inches of snow (at best), I still managed to move about on my wooden skis in the back yard (which was more or less a jungle
), so don't worry about the snow. Just have fun!
if skiing fails, you can always just go for a walk
(Tip: buy a wide thermos, boil hotdogs and put them+ the water in the thermos, it keeps them warm for some time).
