As I enter into full geezerhood I am doing short winter trips (1 or 2 miles max at 9,000+ ft.)
My attitude is better short trips than no trips.
-> First my travel area is kinda limited here in the Las Vegas area Spring Mountains.
-> Second “The spirit is willing but the flesh is weak” as I get well into my 70s.
-> Third I just love winter camping and I have all the Ski Patrol  special training (Avy 1, Winter Travel and Rescue, Mountaineering) and extensive experience in the eastern and the western US (west of the Rockies).
-> Finally I GOT THE GEAR! From -20 F. down bag, insulated mattress, white gas stove or ti Caldera Cone wood stove, winter tents to winter clothing in spades.
It’s going be a good winter for getting into the mountains “…to get their good tidings.” as Muir said.
And when In my 80s it may well be winter car camping – that is if we still have winters by then!
