I have not done any winter camping since boy scout days in Minnesota. Then, we dug snow caves in twenty-degree below zero weather, started a fire at the entrance and stayed up all night feeding the fire.
I'd love to try it again this winter if you have room on any of your trips. Unfortunately, Christmas to New Years is out for me.
