Jim, you are 100% correct but did not venture into the lightweight area. Most of my peak bagging is class 3 walkups. I think the 3 pounds of water and food is a little light. To spend the night, I would take two and a half quarts and a pound and a half of food. That equals 6.5 pounds. Combine that with the following gear list that is very stormworthy and is comfortable down to at least 15 then you still have a pack of less than 15 pounds. Instead of bagging the peak maybe watch sunset and sunrise from the summit.
