Not only were chains needed, but they made you put them on less than a mile into the mountain. Ive never had to put them on that soon. Pretty much right off the freeway. On the way down it wasnt too bad after about half way. It was pouring snow when I left around 3, but I couldnt tell you what the story will be tomorrow. Definitely have the chains on standby though.
I also saw an SUV spin out into the snowbank in my rearview, and an Audi crash into the snowbank two cars ahead of me, both on my way up. It was pretty nasty.
