Were lucky to get the cold days where it sunny and the the dark cold days haha I'm probly not makin any since but it gets really cold in cali-4-nia :-)|||California has mountain peaks that are around 14000 feet. They would get really really cold. So I would say the top of Mt. Shasta might be the coldest place. Just a guess though.|||In SoCal I lived in a town called Pine Mountain Club, CA 93222. The coldest it got at my house way -1.4 degrees.
