Snowmobile novice question

[Steveo]

I know nothing about snowmobiles, been on one once years ago. In looking at the web cams I see very few snowmobile tracks. So I was wondering how difficult is it to ride on top of deep fluffy snow. Do you get bogged down or is it just a s...load of snow in your face. I realize that once it is packed down it is ideal (especially for cooling) but if you get hit with another foot of snow Sunday will people have problems getting through it.
