How to store stuff outside your pack

Reflecting on a trip twenty years ago, the author shares insights on what they would alter, such as hiking later into the day to utilize camping spots better, and creating a detailed pre-trip spreadsheet for trails and sites. They also describe an effective, though simplistic, food routine involving freeze-dried meals and powdered milk that fulfilled their needs well. However, the author notes excessive packing of heavy clothing and inefficiencies in water storage, suggesting modern packs with built-in hydration systems as an upgrade.
