Hello /out/, I need advice for preparing what will likely be a solo Winter Appalachian Trail hike in mid-December, which should last between five to seven days. I've done solo AT hikes before but never in the dead of winter, and since the temperatures at that time of year can get to the single-digits (if not lower if there's a wind chill), I need advice on what I should prepare myself for, via both items that I need to bring (clothing, socks, etc) and miscellaneous tips. I've already sown up loose ends on my 20°F bag and I've added with it a liner that brings it to a 0°F bag, plus I've just bought new trekking poles and Goretex boots, for reference. Thanks!
