Warm and light

Sara and I will be sleeping out during Christmas break. She says she will anyway. We need to test out our sleeping systems. We need to find out how light can we go and still be warm in twenty degree weather. We have to carry these things up and over every mountain pass. We have to carry these things every mile of the race, all the way from Canada to Mexico. So we will go as light as possible. I will be trying out a 9 ounce tent. You might ask how much protection will that give you?". Not much. But it is light.
