"where the Vis could go from 20 miles to 1 foot in seconds."
That sounds familiar, when Northern VA got that 26+ inches of snow not long ago I went up to to visit family and the roads had been cleared....mostly. I-64 was one lane and that was dangerous still, there was so much snow blowing around I couldn't see in front of the car in front of me then it would randomly stop and I could see fine. Scion barely made it up there, wasn't made for snowy roads.
Thanks for the warning about 33, always good to know what I'm up against.
