I'm section hiking NJ in August, (starting at Worthington), & trying really hard to keep my pack weight down to 30 lbs. With seven days of food & one liter of water I'm right at 30 lbs. I will eat 2 lbs of food a day, (7 days of food), allowing me to carry more water as I meander down the trail and still keep to my target weight. My question is about water at the beginning of the trail over the first 20 miles, or two days of walking for me. How available and frequent is reliable water in those first 20 miles? Is it safe to only carry one liter in that section of the trail? Thanks all!
