If you lived in a state where the roads with snow on them almost always go straight up, you would understand the reason for chains. I gaurantee you that if you lived here and had to drive in the mountains in the winter yyou wold have a 4 wheel drive or carry chains. It is a state law for one thing, and where the snow is very wet they are necessary. Try to curb your ignorance until you can ask someone who knows this area about driving conditions before you run your fat mouth.
My my my! What a hissy fit! First of all, in Alaska we have lots of snow and lots of mountains. It goes without saying that most of us have a 4WD. CA seems to have a law for everything. I spent a few years down in CA and I've been to the affected area a number of times. I wouldn't have any qualms about driving my truck on those roads without chains or studded tires all winter long. But I would have had the sense to terminate my journey before I got snowed in. But in CA, taking personal responsibility isn't required. Maybe it's against the law.
