Thinking back on last year's AT trips, and remembered a stretch where I dry camped for three straight nights with only 2L of water each night. Starting this thread to share lessons learned, and let other share tips/experiences.
1) You can camp with only 2L of water, for multiple nights in a row, even in warm, dry weather, without getting dehydrated
+ Note that this only works if the next water source is within a half day's walk. If water sources are further apart than that, you need to carry extra water to hike with the next day.
+ You must be willing to carry an extra 4-6 lbs of water uphill on tired legs at the end of the day.
+ All water should be used for drinking or cooking. Things like washing dishes or brushing teeth can wait until your next refill.
+ Ration your water. Take a sip every few minutes. Don't chug or take long drinks.
+ In warm weather, get up and start hiking early. This will keep sweating to a minimum and allow your body to conserve water.
+ Stop and drink a liter of water when you refill at the next water source. Even if you don't feel like you need it.
2) You can camp anywhere where you can find 10 square feet of flat ground (or two sturdy trees 8-10 feet apart, if you like to hang)
+ Stop and enjoy the sunset and sunrise at that place with the gorgeous view. :-)
+ Of course, camping restrictions should be obeyed where applicable, and designated sites or at least previously used spots are preferred over creating new ones
3) You can experience solitude every night, even on the AT
+ This was the best part of my experience. I loved listening to the sounds of nature instead of human voices. And I woke up one morning to a herd of deer grazing near my campsite.
+ Stopping in between the shelters means they're usually empty by the time you reach them. I stopped for a long break at the first shelter late morning every day and never had any company.
