Back in the day, I enjoyed winter camping. I had the skills, the right equipment and was prepared to turn around if needed. This last point is important since you need to know when to quit.
For example I had (still have) mickey mouse boots that are Army design to keep feet warm. I bought them from Bata Shoe company in Edgewood or Aberdeen Maryland back in the early 80s.
How'd I learn about these boots? From an Hurricane Island Outward Bound trip I took in the early 80s also in the White Mountains of NH. We summitted Mt. MOOSILAUKE. We met in Hanover, NH. It was a great experience.
My borrowed Mickey Mouse boots in New Hampshire.
