My son, Guy with his boys, Jans and Denver. Guy is mixing relish with tunafish and mayonaise to be eaten with crackers for a lunch along the trail. Guy has been in the back country enough with boys to know that you have to feed them a lot of calories to keep their strength up. So they are allowed to eat candy and things that is not okay at home. For me my lunch was a candy bar and Poweraide. Maybe I should do a commerical for Poweraide as it is my favorite drink on the trail. It furnishs me with the calories I need to go on and I am able to drink more than if I drink straight water. I carry concentrate and mix it as I go.
