Thanks for this. I'm doing my first August 4 s a day hike as well. Lost my partner so hoping to find a second to use the extra pass. My wife is worried about going alone but this has eased her qualms a bit. Thought I may have done a bit of overkill when I bought a Camelbak three liter reservoir backpack. Maybe it will save time. Who knew a gallon of water weighs eight pounds?
