An American Question???
 

I'm looking at a map of the US wondering in the winter where the snow fall line is? If you look at the west coast, how far down do you go before you get some reasonable winters?? I've just spent this morning in the warm garden then came in to watch CSI Miami. Its too far a drive to Miami :D for the winter so it raised this question. The tourist information sites aren't really that helpful so can anyone help???
