Very kewl info. 
From what I remember it snowed for about 2 days, then the next day it was sunny with no snow, and then we drove on it the day after that. 
It was the stickiest stuff I have ever seen. Thick, red-maroon colored clay. It was horrible. 
I guess my wife could have buried me there if something would have happened 

I loved all those Porter Rockwell stories.
