Leaving behind the Gatorade is not a good idea. You need the electrolytes when you are working that hard.
I was hit by low salt a couple of summers ago at a camp in west Texas. I was drinking plenty of water, but had headaches and was low on energy. I started salting my food at every meal and was fine after that.
The Probars provide some of that fiber that you need to keep regular on the trail. The Larabars provide the rest.
The sqeezefood was a bother, especially when opened as one-piece trash. I like last year's sliceable cheese food product better. I got better at applying the sunbutter, and found it pretty tasty. It was easier to just squeeze it into your mouth than to apply it to the crackers.
Our crew picked up lots of extra food from swapboxes and ate it all. One evening, they prepared 18 people worth of dinner for 10 people and ate it all.
Note: The freeze-dried corn can be added to nearly any meal. Don't cook it separately, just add it in. Also, refried beans taste OK added to the mac and cheese.
