Leaving town with a full food bag is always a double-edged sword. Your next few days of trail meals are going to be good, but food is very heavy, and after your first steep climb of the day, you’ll want to stop and eat something just to lighten your pack. A good target is 10 to 12 lbs for a 4 or 5 day hike. Try to choose nutitious but light-weight food. As you eat, your pack gets lighter.
Preparing and eating meals on the AT becomes a ritual only a very few will experience. Meal time at a shelter with your fellow hikers is one of the great pleasures of thru-hiking. People from all walks of life have hiked to that spot on the trail and they will share mealtime with you. The smells and flavors of your meal are somehow better after you hauled your food 15 miles and up a mountain or two. Eating is not just something you have to do, but a memorable part of your hike.
In the evening, after you have eaten your dinner and your stomach is full and warm, your muscles will relax and your mind will fill with all you have seen and felt that day.
