There’s a thing called going too far, and not leaving a margin for error.
They’re usually highlighted in the coroner’s report.
That's what the extremists do. They take nothing for backup, zero. They calculate their food and water to the last sip or calorie. They won't take a stove, just food that can be eaten cold. No fire starter other than matches or a single lighter. No extra dry clothes. The goal isn't the hike or the scenery. It's all the game of getting it as light as possible. No thanks.
