Gear, Do I have enough?

I can't sleep. I keep thinking about yaktrax and marine wool and long underwear and polypropylene. I can't stop thinking about if I will be warm enough, to warm, the right sunglasses, enough lens, to much weight, not enough clothes.

Yaktrax are pretty cool by the way. They are rubber slings that go around the sole of your boots. The rubber is wrapped with metal coils to give you good traction on the snow.
