Wayne and Laura,
You had to remind me of my first time over Trail Crest. My back still hurts from the 50+ pounds. I told myself it was 45 at the time but it was closer to 60.
I was using and 80 L, 7 lb. pack and had stuff hanging off for a 7 day trip to Whitney Portal from Horseshoe Meadow...a trip I do today in 3 days.
My current winter snow camping pack weight is less than that haul.
