What you and others might consider if you want to try out snow camping, is to go out late in the season when overnight temps are only getting into the upper twenties at night at the coldest. The only issue then would be if you sleep warm enough with what you brought to sleep in/on. Assuming you don't fall into a creek or lake. Go into an area where other folks frequent for like activities, then as you build confidence and experience expand from there. I go out on solo trips when temps are below zero now and years ago, I would never have entertained the idea. I thought people would have to be crazy, but I have the gear now, after building up my stuff slowly over the years. Still not where I want to be, a few small touches here and there would make the experience warmer.
