This will be an interesting one to follow. Usually the winter PCT discussions are started by the clueless. This hike is being done by Trauma and Pepper. They started October in Canada so it not exactly a winter hike yet. And they are moving at a very fast pace so it is more likely to be a winter JMT hike which I believe both have have already done.
