A friend and I are planning an overnight in January, most likely at the Colden Shelters. I was looking for a few suggestions.
1. I have a zero degree bag and good winter gear, parka, base layers, etc. Assuming it is not unusually cold, anyone see a problem with this (need warmer bag?) I assume I would sleep in basically regular clothes, e.g. full base layer plus fleece pants and a light insulated top and hat.
2. We do not have a 4 season tent. Would you pitch a three season tent in the leanto, just use a bivy sack? What about wind in the shelter, is this typically a problem. What could you even do about it?
Anything else to look out for? I have plenty of winter experience in the Adirondacks and Mt. Washington, just have never gone overnight and thought a one nighter in a lean to would be a reasonable start.
