I slept inside Sunday night --midnight till around 0730. Went outside to measure snow, it was 4.5 inches. Just to kill time I set up a Blackbird on the carport, look at the thermo and it read 19F. Threw a Winter Mamba in the Blackbird and a Te-wa Winter Coat underneath and then lied down.
Next thing you know it was 1:30 in the afternoon.....so even after sleeping in a bed from midnight 'till morning the magic of the Blackbird gave me 5 more hours of sleep!
When I woke I again measured the snow depth...up to 8.5 inches, then I packed up and got off the mountain before I became snowbound!
