Good tips.
I would also add:
-Wind protection. Wind over the bag will wick away body heat. Anywind barrier will save you lots of body heat.
-Wear all your extra clothes or lay extra clothes and gear over your bag.
-In extreme weather, pile pine needles, leaves or pine boughs over your bag for added insulation.
-Pile your gear close around you to keep you from sliding off your insulated pad while you sleep.
-Wear a warm stocking cap while sleeping.


Duty of the Militia (that means you and me):

"The Militia, to Enforce the laws of the Union, to surpress Insurection and repel Invasion. A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."
-Constitution of the United States of America
