72 Hour Survival (no food, no water, on an island)

We spent 72 hours stranded on a deserted island off the coast of Panama with no food or water, bringing only one item each and using primitive survival skills. We built a shelter, started a fire, gathered and opened coconuts for water, and endured intense heat, thirst, crabs, sand flies, and a giant spider. On the second day, we built a bamboo ladder and eventually discovered a source of fresh water.
