Geoff-
Snow in Seattle.. I remember that.. NOT safe.
I'm in wenatchee and I've had mine parked for a couple months and just got it out today!
Snow rules...I took it behind the old Target to their UNplowed parking lot with 4 inches of snow!!
These things really kick some ass on snow. It COULD get stuck, but it sure drifts damn nice.
Get it sideways, Downshift, let off the gas and it swings straight...way better than my old 356, and probably better than a very well outfitted bug!
But i wont risk it much, I'll probably park it again.. ..
