I have changed the overall theme for the site to a more modern "curve" theme. It will be the one everyone uses from now on, you will not be able to alter it on your own. It will make things a whole lot easier for me to maintain.
Stuff sack for the boots are key. I do not do winter camping but have done the same when we camped late Oct in WV (30f or lower at night easy). Dirt and muck are less bad than getting your bag wet in the toe box area.
3) Place the boots in a stuff sack the put them inside the bottom of your sleeping bag.
